Jesus gave the Vatican infaliability with respect to teaching faith and morals. There are sinners in the church, Vatican, and Papacy - it is only the chatechism which is infaliable. Remember - “bind on Earth is bound in Heaven”. This makes the Catholic Church the arbiters of sin.
Wait just a darn minute, here!!! You mean you guys hold to Sola Chatechisma? Does that come from the Bible? If it does, does that mean we have Sola Scriptura proving Sola Chatechisma?
