1,000 years ago???

You were more correct in your title. St Damien was born in 1840 and died in 1889. His writings were from a little more than 100 years ago, and far, far less than 1,000 years ago.
You’re confusing St Damien Veuster with St Peter Damian. Two entirely different people, but both holy men.
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.
