It must be something to be filled with such hatred and bigotry that you refuse to listen to historical fact.
Rather than standing in God’s place as the judge of the Catholic Church worry about your own salvation.
1 John 3:15
Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
When Christ addressed nicolaitanism he was speaking to real Christian congregations, not gnostics.
