Who? You mean Antipope Gus, aka BadBob (the alias he used when he took God's Holy Name in vain), aka Alan Vincent? He called me a heretic once for defending veneration of the Blessed Virgin Mary. He called me a sophist for pointing out the Scriptural exegesis that proves the communion of saints and venerating them and their relics. He called me a schismatic for not professing subjection to him.
At one point he claimed that the anti Jansenist popes had been contradicting the Council of Orange, and were heretics. This really made me research and dig for the answers like I had never dug before, and I was worried he might be right. I eventually came across the key phrase in the letter whereby Boniface II approve the Council, which showed Antipope BobGus to be wrong: "no good at all according to God"
But he claimed I was wrong, only to use the very same argument himself recently to refute someone else!
I am done with debating him. He has proven himself to be a liar on numerous occasions.
In any case, he is a dangerous individual with too much knowledge and ZERO charity.
