If you have a little time today (and it won't take much), I encourage you to read The Confession of St. Patrick. Just to get a little taste of the man first-hand: his self-consciousness about his lack of education, his eagerness to please. "But," as he says at the end, "I entreat those who believe in and fear God, whoever deigns to examine or receive this document composed by the obviously unlearned sinner Patrick in Ireland, that nobody shall ever ascribe to my ignorance any trivial thing that I achieved or may have expounded that was pleasing to God, but accept and truly believe that it would have been the gift of God. And this is my confession before I die."
Happy St. Patrick's Day.
