The Greek manuscripts. It is they which show the Catholic Church to be apostate. Besides, God used Judas, Balaams donkey, and Harrod to further His goals.
Ill give you another.
God says.
Deuteronomy 12:30 Take heed to thyself that thou be not snared by following them, after that they be destroyed from before thee; and that thou enquire not after their gods, saying, How did these nations serve their gods? even so will I do likewise. 31 Thou shalt not do so unto the LORD thy God: for every abomination to the LORD, which he hateth, have they done unto their gods; for even their sons and their daughters they have burnt in the fire to their gods.
But the Catholic Church says.
We need not shrink from admitting that candles, like incense and lustral water, were commonly employed in pagan worship and the rites paid to the dead. But the Church from a very early period took them into her service, just as she adopted many other things indifferent in themselves, which seemed proper to enhance the splendor of religious ceremonial. We must not forget that most of these adjuncts to worship, like music, lights, perfumes, ablutions, floral decorations, canopies, fans, screens, bells, vestments etc. were not identified with any idolatrous cult in particular; but they were common to almost all cults (Catholic Encyclopedia, III, 246.)
Catholics cant deny that the RCC has incorporated pagan practices into its practices. The RCC itself admits that it does. The RCC refuses to hear the words of the Lord.
Its happened before.
As for the word that thou hast spoken unto us in the name of the LORD, we will not hearken unto thee. But we will certainly do whatsoever thing goeth forth out of our own mouth, to burn incense unto the queen of heaven, and to pour out drink offerings unto her, as we have done, we, and our fathers, our kings, and our princes, in the cities of Judah, and in the streets of Jerusalem: for then had we plenty of victuals, and were well, and saw no evil. (Jer.44:16-17)
And how was it that the New Testament canon was determined?
