"There are the ones who claim..."
Stop it already. "Those who claim" are the enemies of the Church and enemies of Jesus Christ.
Someone in error who believes wrong ideas about the nature of God and the Church is one thing.
Someone who is actively seeking to destroy the Church is an execrable demon in human flesh and not worth the time or effort it would take to read and refute their garbage.
You've already said you were serious about saving your soul, but now you're bringing up these heresies again.
You're tempting God. Keep playing next to a rattlesnake den and see what happens. The first chapter of the Epistle to the Romans says that God gives people over to a deranged mind if they won't leave sin and sinful company alone.
Stop asking how to refute nonsense that has never been taught by Holy Church and start reading things that will BUILD your faith.
St. Anthony of Padua, hammer of heretics, terror of Hell, pray for us.
Immaculate Heart of Mary, triumph soon!
Most Sacred Heart of Jesus, have mercy on us.
