I bind to myself today

The strong virtue of the Invocation of the Trinity:

I believe the Trinity in the UnityThe Creator of the Universe.

I bind to myself today

The virtue of the Incarnation of Christ with His Baptism,
The virtue of His crucifixion with His burial,

The virtue of His Resurrection with His Ascension,

The virtue of His coming on the Judgement Day.

I bind to myself todayThe virtue of the love of seraphim,

In the obedience of angels,

In the hope of resurrection unto reward,

In prayers of Patriarchs,

In predictions of Prophets,In preaching of Apostles,

In faith of Confessors,

In purity of holy Virgins,

In deeds of righteous men.

I bind to myself todayThe power of Heaven,

The light of the sun,

The brightness of the moon,

The splendour of fire,

The flashing of lightning,

The swiftness of wind,

The depth of sea,

The stability of earth,

The compactness of rocks.

I bind to myself todayGod's Power to guide me,

God's Might to uphold me,

God's Wisdom to teach me,

God's Eye to watch over me,

God's Ear to hear me,

God's Word to give me speech,

God's Hand to guide me,

God's Way to lie before me,

God's Shield to shelter me,

God's Host to secure me,

Against the snares of demons,

Against the seductions of vices,

Against the lusts of nature,

Against everyone who meditates injury to me,

Whether far or near,

Whether few or with many.

I invoke today all these virtues

Against every hostile merciless power

Which may assail my body and my soul,

Against the incantations of false prophets,

Against the black laws of heathenism,

Against the false laws of heresy,

Against the deceits of idolatry,

Against the spells of women, and smiths, and druids,

Against every knowledge that binds the soul of man.

Christ protect me today

Against every poison, against burning,

Against drowning, against death-wound,

That I may receive abundant reward.

Christ with me,

Christ before me,

Christ behind me,

Christ within me,

Christ beneath me,

Christ above me,

Christ at my right,

Christ at my left,

Christ in the fort, [i.e., at home]

Christ in the chariot seat, [i.e., travelling by land]

Christ in the poop. [i.e., travelling by water]

Christ in the heart of everyone who thinks of me,

Christ in the mouth of everyone who speaks to me,

Christ in every eye that sees me,

Christ in every ear that hears me.

I bind to myself todayThe strong virtue of an invocation of the Trinity,

I believe the Trinity in the UnityThe Creator of the Universe.

This rather literal version is found in Philip Schaff's, History of the Christian Church, Vol. 4, §14. Schaff, notes that this Irish hymn is found in the Book of Armagh , and is "called S. Patricii Canticum Scotticum, which Patrick is said to have written when he was about to confront and convert the chief monarch of the island, Laoghaire /Loegaire.
