Can the Fraticelli Pope make Saints? I have A Fraticelli Pope whom is my Vassal in Ireland mainland Europe is still Catholic so the Heresy hasn't replaced Catholicism,

My Ruler had all the virtues 12k piety and established the Papacy so the pope had over 100 opinion of the guy.

He died in 997 it's now 1000 will this pope declare him blessed or even a saint? is he even able to?
