Oh, I agree. The way we know that something is heresy is by judging from the only objective and authoritative source we have, the Holy Bible. It was one of God's wonderful gifts to us, his church, so that we will know the truth.
And heretics claim the same. Their word against ours. Boatbums vs. FReeperZ each with the same authority - none.
Without the creeds determined by the authority of His Church without His Church's authority there can be no One Faith, no One Universal, Holy and Apostolic Church.
thanks for your reply.
