It's not a priest. He's saying "say your prayers and comb your hair" obviously what a parent says to their child. "you need a place to hide" is saying that he "practices what he preaches" out among the world, being a good christian, but when the doors are closed he is anything but, because he is abusive (not necessarily sexually). "you confess it all away, but it's only shit to me" The father believes that by going to confession, it wipes the sins away. But not in the child's eyes. "the innocence you spoiled, found a way to live" Children are innocent, meaning they are free from worry, and sin, and morality. These are all things we are taught, or pick up on. He was forced to learn earlier than most, and though he doesn't maintain the "forced beliefs" from his father, he has still managed to grow into an adult with a concept of right and wrong.
Now for the stretch. "when your worlds come crashing down" I think is referring to the apocolypse. Where he subsequently says "I want to relive" and "Let me be the one to say, I'm not Jesus and you can't run away" Going back to the "child-abusing, turned-satanic" leads me to believe that his father has broken away from his religious beliefs and the "child" here is saying that if the father was right to begin with, and there is an "end of the world" He wants to "relive" through the tribulation period and seek out his father (who would be there having abandoned Jesus) and exact his revenge, because He may be able to turn from Jesus without immediate consequence, but he can't run from me (the abused child).
