Saint David of Wales (601)

He was the disciple of a Saint Paulinus, an apostle to England. Saint David is the patron of Wales, where thousands and thousands of noble Catholics have lived and where many saints have been given to God. Saint David was a most militant adversary of all heresy, especially that of Pelagius, a Briton, who held that grace is not necessary for the performance of good works and that mere natural virtues can lead one to salvation. Saint David of Wales died when he was one hundred and forty-seven years old.
