You're referencing St. Damien of Molokai - Hawaii (1840-1889) who was a medical doctor and missionary to the lepers.
I'm referencing St. Peter Damian, of Italy (998-1073) Monastic Reformer, Bishop, Cardinal, and Doctor of the Church, who preached and wrote against --- among other things --- the triple vices of Usury, Luxury and Sodomy.
Ah, mea culpa
However, in my defense St Damian of Italy is normally referred to as either St Peter Damian or Peter Damian, and not just St Damien/Damian.
