It was the charge of the Reformers that the Catholic doctrines were not primitive, and their pretension was to revert to antiquity. But the appeal to antiquity is both a treason and a heresy. It is a treason because it rejects the Divine voice of the Church at this hour, and a heresy because it denies that voice to be Divine... I may say in strict truth that the Church has no antiquity....Primitive and modern are predicates, not of truth, but of ourselves...The only Divine evidence to us of what was primitive is the witness and voice of the Church at this hour. . — Most Rev. Dr. Henry Edward Cardinal Manning, Lord Archbishop of Westminster, The Temporal Mission of the Holy Ghost: Or Reason and Revelation (New York: J.P. Kenedy & Sons, originally written 1865, reprinted with no date), pp. 227-228.

Thats about it..They mock salvation by faith alone... and then they swallow everything Rome says by “faith alone”. Like the Mormons and the JW’s their prophet has the entire truth..
