So coy.
Your PERFECT church; with it's PERFECT doctrine; could not even get those seven churches in ASIA right!
If there were an Internet back then, Catholics would be howling for Pete's head; just like they are Francis' head today!!!
Nobody every denied that the Catholic Church has faced these problems from Day One. The Church has never held that all her people and all her local churches are perfect. If that were the case, we wouldn't start every Mass by saying we confess our sins, and proclaim before every Communion, "O Lord, I am no worthy."
So you're refuting a definition of "perfection" that the Church has never held.
