That's interesting, I didn't know that was the Catholic position. We're probably not really too far apart on this, as I don't think small children are held accountable either. As you may very well also, I just know from personal experience that they are capable of making decisions, even to the point of repeating them over and over when they know darn well better. :)
FK: I love invincible ignorance.
You're losing it rapidly...
BWAHAHAHAHA! But when it comes to new and different ways of being ignorant, you'll find that I am a rather resourceful fellow. Just ask my wife. :)
Except, that it does not fit into your "double-predestination" belief. If a child commits sin it is no different than, say, Judas betraying Christ. They both commit evil because it is "in God's plan" and "for His purpose."
