My conformation saint, saint Thomas Aquinas. Before I was baptised I have heard a lot about him and was bombarded with quotes from his summa in seremons I was listening to, so I've learned a lot of him. I also admire his story of how he was locked up in a castle and tempted by a prostitute
My countryman, saint Maximilian Maria Kolbe. The main reason I like him is that he shows me the joy God can give us. His letters from Auschwitz sound as if he was on vacation.
One of my favourite popes, blessed Pius IX. His story of trying to appease the liberals and being betrayed by them should be taught to every Christian, to remind us, that our enemies hate us to the core and will not be satisfied untill the last one of us rejects Christ.
