Proud Catholics humbled
Catholics claim legitimacy by way of inheritance of the priestly offices, and by the unity of the faith.
Both of these were broken in the Great Schism. East and West churches disagreed if the Spirit proceeded from the Father or the Father and the Son. The popes declared each other anathema, or cursed.
Catholicism lost any claim to truth when their unity was destroyed.
Now they have the reputation as those who deified Mary, conquered the laity, taught Balaamisms, and imported legalism from the Judaisers, killed those who didn't believe them, hid scriptures for 1200 years, and have a long history of pedophilia.
Any ritual you perform to receive grace is pagan. Baptism is the preaching of the cross in symbols, as are the other 'sacraments'. Nicolaitans (conquerors of the laity) want power over you, so they insist that they are the dispensers of grace in those rituals.
