I’m not Catholic but I do agree with them when it comes to the Saints and in the belief that we have a great cloud of witnesses that surround us. And of all the saints (and there are some good ones, I really dig St. Francis of Assisi), my favorite is St. Patrick.
He made no distinction of classes in his preaching and was himself ready for imprisonment or death. He was the first writer to condemn all forms of slavery.
This point about Patrick being the first writer to condemn slavery was discussed in more detail in the book How the Irish Saved Civilization – by Thomas Cahill
