Simply put you follow the bad tree it was established by Satan and not Jesus. It teaches false doctrines, it has extremely bad fruit and it harms the flock. This proves you are separated from the church Jesus established.Simple put, they are wrong because they separated from the Church Christ established 1,500 years earlier.
That is your personal fallible opinion.
How is it that you can't even see the obvious -- you follow the opinions of men.
before you would have any possible claim to them
If you don't want to understand Christ's Catholic Church, what are you doing here?
Again, you won't find the keys going to the other apostles or to you in scripture. You have made that up out of thin air.
CCC 881 The Lord made Simon alone, whom he named Peter, the "rock" of his Church. He gave him the keys of his Church and instituted him shepherd of the whole flock [Cf. Mt 16:18-19; Jn 21:15-17]. "The office of binding and loosing which was given to Peter was also assigned to the college of apostles united to its head" [LG 22; cf. Mt 18:18; Jn 20:21-23]. This pastoral office of Peter and the other apostles belongs to the Church's very foundation and is continued by the bishops under the primacy of the Pope.
You follow men and their opinions and that is because you follow wolves in sheep's clothing and they do love to dress up.
