The keys of the kingdom of God has been given to anyone who is in union with Christ the 2nd Adam and I get to make use of those keys each and every day as one of God's sons upon the Earth, and yes the Catholic Church overall is extremly heretical! I have a right to say that with great boldness and confidence because me and my family were part of it years ago but the Lord Himself set us free, me in 1994 once I was Born Again and my wonderful mother years before that when she was Born Again and then my father as well as my sister, all of them with Jesus today because of the New Birth!
