A prayer of St Thomas Aquinas

O God, who in this wondrous sacrament hast left unto us a memorial of thy passion;
grant us so to venerate the sacred mysteries of thy body and blood,
that we may ever continue to feel within ourselves the blessed fruit of thy redemption.
Who livest and reignest one God, for ever and ever.

Lead Us

Lead us, O God, from the sight of the lovely things of the world
To the thought of thee their Creator;
And grant that delighting in the beautiful things of thy creation,
we may delight in thee, the first author of beauty
and the Sovereign Lord of all thy works, blessed for evermore.

Daily Prayers

Sweet Jesus

Sweet Jesus, Body and Blood most Holy,
be the delight and pleasure of my soul,
my strength and salvation in all temptations,
my joy and peace in every trial,
my light and guide in every word and deed,
and my final protector in death.

Amen.

Grant to me…

Grant me, O Lord my God,
a mind to know you,
a heart to seek you,
wisdom to find you,
conduct pleasing to you,
faithful perseverance in waiting for you,
and a hope of finally embracing you.

Amen.

Grant me…

O Merciful God,
grant that I may ever perfectly
do Your Will in all things.
Let it be my ambition to work
only for Your honour and glory.

Let me rejoice in nothing
but what leads to You,
nor grieve for anything
that leads away from You.

May all passing things
be as nothing in my eyes,
and may all that is Yours
be dear to me,
and You, my God,
dear above them all.

May all joy be
meaningless without You
and may I desire
nothing apart from You.
May all labour and toil
delight me when it is for You.

Make me, O Lord,
obedient without complaint,
poor without regret,
patient without murmur,
humble without pretence,
joyous without frivolity,
and truthful without disguise.

Give me, O God,
an ever watchful heart
which nothing can ever
lure away from You;
a noble heart,
which no unworthy affection
can draw downwards to the earth;
an upright heart,
which no evil can warp;
an unconquerable heart,

Grant Me Grace

Grant me grace, O merciful God,
to desire ardently all that is pleasing to Thee,
to examine it prudently,
to acknowledge it truthfully,
and to accomplish it perfectly,
for the praise and glory of Thy name.

Amen.

The Holy Cross

The Cross is my sure salvation.
The Cross I ever adore.
The Cross of my Lord is with me.
The Cross is my refuge.

Before study or class

O Merciful God, grant that I may eagerly desire,
carefully search out, truthfully acknowledge,
and ever perfectly fulfill all things which are pleasing to Thee,
to the praise and glory of Thy name.

Amen.

I Thank You Holy Lord

I thank you, O holy Lord,
almighty Father, eternal God,
who have deigned,
not through any merits of mine,
but out of the condescension of Your goodness,
to satisfy me a sinner,
Your unworthy servant,
with the precious Body and Blood of Your Son,
our Lord Jesus Christ.
I pray that this Holy Communion
be not a condemnation to punishment for me,
but a saving plea to forgiveness.
May it be to me the armor of faith
and the shield of a good will.
May it be the emptying out of my vices
and the extinction of all lustful desires;
an increase of charity and patience,
of humility and obedience, and all virtues;
a strong defense against the snares of all my enemies,
visible and invisible;
the perfect quieting of all my evil impulses of flesh and spirit,
binding me firmly to You, the one true God;
and a happy ending of my life.
I pray too that You will deign to bring me, a sinner,
to that ineffable banquet where You with Your Son and the Holy Spirit,
are to Your Saints true light,
fulfillment of desires, eternal joy,
unalloyed gladness, and perfect bliss.
Through the same Christ our Lord.

Amen

For Ordering a Life Wisely

St. Thomas recited this daily before the image of Christ

O merciful God, grant that I may desire ardently, search prudently, recognize truly, and bring to perfect completion whatever is pleasing to You for the praise and glory of Your name.

Put my life in order, O my God.

Grant that I may know what You require me to do.
Bestow upon me the power to accomplish Your will, as is necessary and fitting for the salvation of my soul.

Grant to me, O Lord my God, that I may not falter in times of prosperity or adversity, so that I may not be exalted in the former, nor dejected in the latter.

May I not rejoice in anything unless it leads me to You; may I not be saddened by anything unless it turns me from You.

May I desire to please no one, nor fear to displease anyone, but You.
May all transitory things, O Lord, be worthless to me and may all things eternal be ever cherished by me.

May any joy without You be burdensome for me and may I not desire anything else besides You.

May all work, O Lord, delight me when done for Your sake and may all repose not centered in You be ever wearisome for me.

Grant unto me, my God, that I may direct my heart to You and that in my failures I may ever feel remorse for my sins and never lose the resolve to change.

O Lord my God, make me submissive without protest, poor without discouragement, chaste without regret, patient without complaint, humble without posturing, cheerful without frivolity, mature without gloom, and quick-witted without flippancy.

O Lord my God, let me fear You without losing hope, be truthful without guile, do good works without presumption, rebuke my neighbor without haughtiness, and—without hypocrisy—strengthen him by word and example.

Give to me, O Lord God, a watchful heart, which no capricious thought can lure away from You.

Give to me a noble heart, which no unworthy desire can debase.

Give to me a resolute heart, which no evil intention can divert.

Give to me a stalwart heart, which no tribulation can overcome.

Give to me a temperate heart, which no violent passion can enslave.

Give to me, O Lord my God, understanding of You, diligence in seeking You, wisdom in finding You, discourse ever pleasing to You, perseverance in waiting for You, and confidence in finally embracing You.

Grant that with Your hardships I may be burdened in reparation here, that Your benefits I may use in gratitude upon the way, that in Your joys I may delight by glorifying You in the Kingdom of Heaven.

You Who live and reign, God, world without end. Amen.

Prayer for a Good Life

Grant O merciful God, that I may ardently desire, carefully examine, truly know and perfectly fulfill those things that are pleasing to You and to the praise and glory of Your holy name.

Direct my life, O my God, and grant that I might know what you would have me to do and for me to fulfill it as is necessary and profitable to my soul.

Grant to me, O Lord my God, that I may not be found wanting in prosperity or in adversity and that I may not be lifted up by one nor cast down by the other.

May I find joy in nothing but what leads to You and sorrow in nothing but what leads away from You.

May I seek to please no one or fear to displease anyone, save only You.

Grant to me, O Lord God,
– a vigilant heart that no subtle speculation may ever lead me from You;
– a noble heart that no unworthy affection may draw me from You;
– an upright heart that no evil purpose may turn me from you.

Give me a steadfast heart that no tribulation may shatter and a free heart that no violent affection may claim as its own.

And finally, grant me O Lord my God, a mind to know you, diligence to seek you, wisdom to find you.

Give me a way of life pleasing to You; perseverance to trust and await You in confidence that I shall embrace You at the last. Amen.

Prayer Before Study #2

O ineffable Creator,
Who, out of the treasure of Thy wisdom,
hast ordained three hierarchies of Angels,
and placed them in wonderful order above the heavens,
and hast most wisely distributed the parts of the world;
Thou, Who are called the true fountain of light and wisdom,
and the highest beginning,
vouchsafe to pour upon the darkness of my understanding,
in which I was born,
the double beam of Thy brightness,
removing from me all darkness of sin and ignorance.
Thou, Who makest eloquent the tongue of the dumb,
instruct my tongue,
and pour on my lips the grace of Thy blessing.
Give me quickness of understanding,
capacity of retaining,
subtlety of interpreting,
facility in learning,
and copious grace of speaking.
Guide my going in,
direct my going forward,
accomplish my going forth;
through Christ our Lord.

Amen.

Marian Prayers

Our Lady of Studies

O Mary, Seat of Wisdom, so many persons of common intellect
have made through your intercession admirable progress in their studies.

I hereby choose you as guardian and patron of my studies.
I humbly ask You to obtain for me the grace of the Holy Spirit,
so that from now on I could understand more quickly,
retain more readily, and express myself more fluently.
May the example of my life serve to honour you
and your Son, Jesus.

Amen.

To the Most Blessed Virgin Mary

0 most blessed and sweet Virgin Mary,
Mother of God, filled with all tenderness,
Daughter of the most high King,
Lady of the Angels,
Mother of all the faithful,
On this day and all the days of my life,
I entrust to your merciful heart my body and my soul,
all my acts, thoughts, choices,
desires, words, deeds,
my entire life and death,
So that, with your assistance,
all may be ordered to the good
according to the will of your beloved Son,
our Lord Jesus Christ.

From your beloved Son,
request for me the grace to resist firmly
the temptations of the world, the flesh and the devil.

My most holy Lady,
I also beseech you to obtain for me
true obedience and true humility of heart
So that I may recognize myself truly
as a sinner, wretched and weak,
and powerless,
without the grace and help of my Creator
and without your holy prayers.

Obtain for me as well,
O most sweet Lady,
true charity with which
from the depths of my heart
I may love your most holy Son, our Lord Jesus Christ,
and, after Him,
love you above all other things.

Grant, O Queen of Heaven,
that ever in my heart
I may have fear and love alike
for your most sweet Son.

I pray also that, at the end of my life,
you, Mother without compare,
Gate of Heaven and Advocate of sinners,
will protect me with your great piety and mercy.

and obtain for me,
through the blessed and glorious Passion of your Son
and through your own intercession,
received in hope,
the forgiveness of all my sins.

When I die in your love and His love,
may you direct me
into the way of salvation and blessedness.

Amen.

Marian Prayer #2

Virgin full of goodness,
Mother of mercy,
I entrust to you my body and my soul,
my thoughts and my actions,
my life and my death.
My Queen,
come to my aid
and deliver me from the snares of the devil.
Obtain for me the grace of loving
my Lord Jesus Christ, your Son,
with a true and perfect love,
and after him,
O Mary,
of loving you with all my heart
and above all things.

Amen.

To Acquire the Virtues

O God, all-powerful and all-knowing, without beginning and without end, You Who are the source, the sustainer, and the rewarder of all virtues, grant that I may abide on the firm ground of faith, be sheltered by an impregnable shield of hope, and be adorned in the bridal garment of charity. Grant that I may through justice be subject to You, through prudence avoid the beguilements of the devil, through temperance exercise restraint, and through fortitude endure adversity with patience.

Grant that whatever good things I have, I may share generously with those who have not and that whatever good things I do not have, I may request humbly from those who do. Grant that I may judge rightly the evil of the wrongs I have done and bear calmly the punishments I have brought upon myself, and that I may never envy my neighbor’s possessions and ever give thanks for Your good things.

Grant that I may always observe modesty in the way I dress, the way I walk, and the gestures I use, restrain my tongue form frivolous talk, prevent my feet from leading me astray, keep my eyes from wandering glances, shelter my ears from rumors, lower my gaze in humility, lift my mind to thoughts of heaven, contemn all that will pass away, and love You only.

Grant that I may subdue my flesh and cleanse my conscience, honor the saints and praise You worthily, advance in goodness, and end a life of good works with a holy death. Plant deep in me, Lord, all virtues, that I might be devout in divine matters, discerning in human affairs, and burdensome to no one in fulfilling my own bodily needs. Grant to me, Lord, fervent contrition, pure confession, and complete reparation. Order me inwardly through a good life, that I might do what is right and what will be meritorious for me and a good example of others.

Grant that I may never crave to do things impulsively, nor disdain to do what is burdensome, lest I begin things before I should or abandon them before finishing. Amen.

Prayer For Mass

A Prayer Before Mass

Almighty and everlasting God,
behold I come to the Sacrament of Thine only-begotten Son,
our Lord Jesus Christ:
I come as one infirm to the physician of life,
as one unclean to the fountain of mercy,
as one blind to the light of everlasting brightness,
as one poor and needy to the Lord of heaven and earth.
Therefore I implore the abundance of Thy measureless bounty
that Thou wouldst vouchsafe to heal my infirmity,
wash my uncleanness,
enlighten my blindness,
enrich my poverty and clothe my nakedness,
that I may receive the Bread of Angels,
the King of kings, the Lord of lords,
with such reverence and humility,
with such sorrow and devotion,
with such purity and faith,
with such purpose and intention
as may be profitable to my soul’s salvation.
Grant unto me, I pray,
the grace of receiving not only the Sacrament of our Lord’s Body and Blood,
but also the grace and power of the Sacrament.
O most gracious God,
grant me so to receive the Body of Thine only-begotten Son,
our Lord Jesus Christ,
which He took from the Virgin Mary,
as to merit to be incorporated into His mystical Body,
and to be numbered amongst His members.
O most loving Father,
give me grace to behold forever
Thy beloved Son with His face at last unveiled,
whom I now purpose to receive under the sacramental veil here below.

Amen.

 

A Prayer before Mass #2

Almighty and ever-living God,
I approach the sacrament
of Your only-begotten Son
Our Lord Jesus Christ,
I come sick to the doctor of life,
unclean to the fountain of mercy,
blind to the radiance of eternal light,
and poor and needy to the Lord
of heaven and earth.
Lord, in your great generosity,
heal my sickness,
wash away my defilement,
enlighten my blindness, enrich my poverty,
and clothe my nakedness.
May I receive the bread of angels,
the King of kings and Lord of lords,
with humble reverence,
with the purity and faith,
the repentance and love,
and the determined purpose
that will help to bring me to salvation.
May I receive the sacrament
of the Lord’s Body and Blood,
and its reality and power.

Kind God,
may I receive the Body
of Your only-begotten Son,
our Lord Jesus Christ,
born from the womb of the Virgin Mary,
and so be received into His mystical body
and numbered among His members.

Loving Father,
as on my earthly pilgrimage
I now receive Your beloved Son
under the veil of a sacrament,
may I one day see him face to face in glory,
who lives and reigns with You for ever.

Amen.

After Communion

I give thanks to Thee, O Lord, most holy,
Father almighty, eternal God,
that Thou hast vouchsafed,
for no merit of mine own,
but out of Thy pure mercy,
to appease the hunger of my soul
with the precious body and blood of Thy Son,
Our Lord Jesus Christ.
Humbly I implore Thee,
let not this holy communion
be to me an increase of guilt unto my punishment,
but an availing plea unto pardon and salvation.
Let it be to me the armour of faith
and the shield of good will.
May it root out from my heart all vice;
may it utterly subdue my evil passions
and all my unruly desires.
May it perfect me in charity and patience;
in humility and obedience;
and in all other virtues.
May it be my sure defence
against the snares laid for me by my enemies,
visible and invisible.
May it restrain and quiet all my evil impulses,
and make me ever cleave to Thee
Who art the one true God.
May I owe to it a happy ending of my life.
And do Thou, O heavenly Father,
vouchsafe one day to call me, a sinner,
to that ineffable banquet,
where Thou, together with Thy Son and the Holy Ghost,
art to Thy saints true and unfailing light,
fullness of content,
joy for evermore,
gladness without alloy,
consummate and everlasting happiness.
Through the same Christ our Lord.

Amen.

 

 

 

Thanksgiving After Mass

LORD, Father all-powerful,
and ever-living God,
I thank Thee,
for even though I am a sinner,
Thy unprofitable servant,
not because of my worth,
but in the kindness of Thy mercy,
Thou hast fed me with the precious Body
and Blood of Thy Son,
our Lord Jesus Christ.

I pray that this holy communion
may not bring me condemnation
and punishment but forgiveness and salvation.

May it be a helmet of faith
and a shield of good will.

May it purify me from evil ways
and put an end to my evil passions.

May it bring me charity and patience,
humility and obedience,
and growth in power to do good.

May it be my strong defense against all my enemies,
visible and invisible,
and the perfect calming of all my evil impulses,
bodily and spiritual.

May it unite me more closely to Thee,
the one true God
and lead me safely through death
to everlasting happiness with Thee.

And I pray that Thou willest lead me,
a sinner to the banquet
where Thou with Thy Son and Holy Spirit,
are true and perfect light,
total fulfillment,
everlasting joy,
gladness without end,
and perfect happiness to Thy saints.

Grant this through Christ our Lord.

Amen.

Prayer of St. Thomas Aquinas for a Holy Life

Grant me, O merciful God, that what is pleasing to Thee I may ardently desire, prudently examine, truthfully acknowledge, and perfectly accomplish for the praise and glory of Thy name. Ordain, O my God, my whole life, and what Thou requirest that I should do, grant me to know it and to fulfill as is meet and profitable to my soul. Give me Thy grace, O Lord my God, that I may not fail in prosperity or in adversity, avoiding pride in the former and discouragement in the latter. May I rejoice in nothing but what leads to Thee, grieve for nothing but what turns away from Thee. May I wish to please or displease no one but Thee.

May I despise, O Lord, all transitory things, and prize only that which is eternal. May I shun ant joy that is without Thee, nor wish for anything outside of Thee. May I delight in any work taken up for Thee, and tire of any rest which is without Thee. Grant me, O my God, to direct my heart toward Thee, and in my failings constantly grieve, with the purpose of a amendment.

Make me, O Lord, my God, obedient without contradiction, poor without depression, chaste without corruption patient without murmuring, humble without pretence, cheerful without dissipation, mature without dullness, prompt without levity, fearing Thee without despair, truthful without duplicity, doing good without presumption, correcting my neighbor without haughtiness, and edifying him by word and example without hypocrisy. Give me, O Lord God, a watchful heart, which no curious thought will turn away from Thee; a noble heart, which no unworthy affection will drag down; a righteous heart, which no irregular intention will twist aside; a firm heart, which no tribulation will break; a free heart, which no violent affection will claim for itself.

Grant me finally, O Lord my God, science in knowing Thee, diligence in seeking Thee, wisdom in finding Thee, a conduct pleasing to Thee, a perseverance trustfully awaiting Thee, and a confidence finally embracing Thee. May I endure Thy punishments by penitence; profit by Thy benefits by grace in this world, and enjoy Thy blessedness by glory in the next; Who livest and reignest, true God, forever and ever. Amen
