[quote=Thal59]>>>Does anyone here believe that any form of Protestantism contains the complete faith that was taught by the Apostles? <<<
No, they do not. Even “watered-down” as some have suggested is too complimentary. Many Protestant faiths, when one considers their doctrines and interpretations, seem to be based entirely on an anti-Catholic stance; i.o.w, if the Catholics accept it, we reject it.
Now if the RCC has the fullness of truth, and one has a propensity to do anything and everything counter to that church because of prejudice, hatred, or bias, then one is guaranteed to have virtually no truth at all.
That’s pretty accurate. Protestantism is worse than just “lacking” something: it is a heresy; and Protestants are heretics. Protestants have no faith at all. Anyone who rejects one single dogma of the Catholic Church loses absolutely all faith, if they ever had it to begin with.
Pope Leo XIII, Satis Cognitum: "Faith, as the Church teaches, is “that supernatural virtue by which, through the help of God and through the assistance of His grace, we believe what he has revealed to be true, not on account of the intrinsic truth perceived by the natural light of reason, but because of the authority of God Himself, the Revealer, who can neither deceive nor be deceived” (Conc. Vat., Sess. iii., cap. 3). If then it be certain that anything is revealed by God, and this is not believed, then nothing whatever is believed by divine Faith: for what the Apostle St. James judges to be the effect of a moral deliquency, the same is to be said of an erroneous opinion in the matter of faith. “Whosoever shall offend in one point, is become guilty of all” (Ep. James ii., 10). Nay, it applies with greater force to an erroneous opinion. For it can be said with less truth that every law is violated by one who commits a single sin, since it may be that he only virtually despises the majesty of God the Legislator. But he who dissents even in one point from divinely revealed truth absolutely rejects all faith, since he thereby refuses to honour God as the supreme truth and the formal motive of faith. “In many things they are with me, in a few things not with me; but in those few things in which they are not with me the many things in which they are will not profit them” (S. Augustinus in Psal. liv., n. 19). And this indeed most deservedly; for they, who take from Christian doctrine what they please, lean on their own judgments, not on faith; and not “bringing into captivity every understanding unto the obedience of Christ” (2 Cor. x., 5), they more truly obey themselves than God. “You, who believe what you like, believe yourselves rather than the gospel” (S. Augustinus, lib. xvii., Contra Faustum Manichaeum, cap. 3).
By not gathering with Jesus in His Church and believing what He has revealed, Protestants have been scattered and are, objectively speaking, enemies of God.
