Feast of Saint PatrickAncient Saint Patrick's Day PrayerO God,
by whose providence the blessed Patrick
was chosen to be the apostle of the Irish;
that thus the people of Hibernia,
who had gone astray in darkness
and in the errors of the Gentiles,
might be made children of the Most High
by the laver of regeneration:
Grant, we beseech thee,
that by his intercession,
we may hasten without delay
to the paths of justice.
Through Christ our Lord. Amen.
From the Breviary of Armagh, cited in The Liturgical Year: Vol. 5
Breastplate of Saint PatrickI bind unto myself today
The strong name of the Trinity,
By invocation of the same,
The Three in One and One in Three.
I bind this day to me for ever,
By power of faith, Christ's Incarnation;
His baptism in the Jordan River;
His death on cross for my salvation;
His bursting from the spicèd tomb;
His riding up the heavenly way;
His coming at the day of doom;
I bind unto myself today.
I bind unto myself the power
Of the great love of the Cherubim;
The sweet 'Well done' in judgment hour;
The service of the Seraphim,
Confessors' faith, Apostles' word,
The Patriarchs' prayers, the Prophets' scrolls,
All good deeds done unto the Lord, And purity of virgin souls.
I bind unto myself today
The virtues of the starlit heaven,
The glorious sun's life-giving ray,
The whiteness of the moon at even,
The flashing of the lightning free,
The whirling wind's tempestuous shocks,
The stable earth, the deep salt sea,
Around the old eternal rocks.
I bind unto myself today
The power of God to hold and lead,
His eye to watch, His might to stay,
His ear to hearken to my need.
The wisdom of my God to teach,
His hand to guide, his shield to ward,
The word of God to give me speech,
His heavenly host to be my guard.
Against the demon snares of sin,
The vice that gives temptation force,
The natural lusts that war within,
The hostile men that mar my course;
Or few or many, far or nigh,
In every place and in all hours
Against their fierce hostility,
I bind to me these holy powers.
Against all Satan's spells and wiles,
Against false words of heresy,
Against the knowledge that defiles,
Against the heart's idolatry,
Against the wizard's evil craft,
Against the death-wound and the burning
The choking wave and the poisoned shaft,
Protect me, Christ, till thy returning.
Christ be with me, Christ within me,
Christ behind me, Christ before me,
Christ beside me, Christ to win me,
Christ to comfort and restore me,
Christ beneath me, Christ above me,
Christ in quiet, Christ in danger,
Christ in hearts of all that love me,
Christ in mouth of friend and stranger.
I bind unto myself the name,
The strong name of the Trinity;
By invocation of the same.
The Three in One, and One in Three,
Of whom all nature hath creation,
Eternal Father, Spirit, Word: Praise to the Lord of my salvation,
salvation is of Christ the Lord.

Saint Patrick's Day Collect Almighty God,
who in your providence chose your servant Patrick
to be the apostle of the Irish people,
to bring those who were wandering in darkness and error
to the true light and knowledge of you:
Grant us so to walk in that light,
that we may come at last to the light of everlasting life;
through Jesus Christ our Lord,
who lives and reigns with you and the Holy Spirit,
one God, now and ever.

A Prayer to Saint PatrickApostle sent by God to Ireland,
in your humility you called yourself a sinner,
but you became a most successful missionary
and prompted countless pagans
to follow the Savior.
Many of their descendants in turn
spread the Good News in numerous foreign lands.
Through your powerful intercession with God,
obtain the missionaries we need to continue the word you began.

Picture my daughter took of one of the swamps near our house. She used the negative setting on her phone to take it.
