from 8th century/part of St. Patrick's breastplate

Christ beside me
Christ before me
Christ behind me
Christ within me
Christ beneath me
Christ above me
Christ on my right hand
Christ on my left

Christ where I lie
Christ where I sit
Christ where I rise

.....

Today I put on
a terrible strength
invoking the Trinity
confessing the Three
with faith in the One
as I face my Maker.
