This is beyond absurd. By your lights the early Church Fathers (theologians) were vipers etc... who assembled the authentic Word of God. This is the sad rebuttal of Protestants who are accustomed to swimming in the very shallow end of the theological pool, taken them to the deep end of the pool they down.
Thus the great saints and theologians of our times, the martyrs, and stigmatists all got it wrong until the curse of Protestantism came upon the earth ELEVEN centuries after the Synod of Rome in AD 382.
The point of course, is that the more true and honest scholarship inquiry takes place, Protestantism is exposed for what its worth, a shallow and erroneous view of scripture from the vapid interpretations of Billy Graham to Jim Jones and David Koresh and everything else in between. This is all fine for low-information Christians but pleas refrain from telling the Catholic Church with its rich tradition of towering intellectuals and theologians what is God’s Word. That is too much effrontery to bear.
The oracles of God were entrusted to the Jews not the Catholics. Already by 96AD when Revelation was written 85% of the churches were already off track. Relying on anyone after that is risky at best.
