Blessed St. Patrick's Day!
From 'St. Patrick's Breastplate Prayer':
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. Amen.
