The Mormon doctrine of the Great Apostasy is devoid of biblical evidence. They have about twenty or twenty-five proof texts for it, none of which come close to establishing a total apostasy, and many, such as Amos 8:11-12 and 2 Thess 2:3-4, if carefully examined, teach the opposite. A good review of the Mormon Biblical arguments can be found in Isaiah Bennett’s book Inside Mormonism. He lists each of the prominent proof-texts used by the the Church of Jesus Christ of Latter-day Sainst and gives an exegesis of each that proves devastating for the Mormon position. I do have some criticism for other parts of Bennett’s book, and he does miss a spot here and there. But he is almost exhaustive, and the two or three Mormon proof-texts that he overlooks can be easily answered by anyone who has read and thought through the verses that he does cover.
Catholics are sometimes surprised that Mormons are not easily impressed by some of the Biblical passages that we use to demonstrate the error of the Great Apostasy. One (but not the only) reason for this is that Catholics are not always know the right details of LDS Apostasy doctrine, and therefore do not clearly show the Mormons how the relevant verses connect point-for-point with LDS teaching.
A crucial feature of the Great Apostasy, which Catholics need to be aware of and actively engage in their discussions with Mormons, is that* the falling away of the Church entailed a removal of priesthood authority from the earth*. No matter how a plain a given text may seem to a Catholic, it will not look convincing to a Mormon unless the Catholic shows what it has to do with the priesthood as Mormons conceive of it. Catholics are so used to responding to Protestants by arguing that the Church cannot fail, they do not realize that for Mormons the winning thesis is that the *priesthood *cannot be removed from the earth. This is a costly oversight, particularly because the perpetuity of the priesthood is actually more explicit in Scripture than is the perpetuity of the Church.
Many texts prove this, but the one that I think takes the least skill to argue is a prophecy in Jer 33. Before showing this passage to a Mormon, it is helpful but not necessary to review a few key points:
(1) the Church is Zion, the Kingdom of God;
(2) Christ inherits the Kingdom as the Son of David;
(3) God is absolutely faithful to his covenants even in the case of human failure. For instance, when he swear to give Abraham innumerable descendants as a reward for his faith fidelity, then it is a done deal. Even if Abraham’s descendants sin, and are rejected by God, then God will still find a way to make good on his pledge.
Mormons are not likely to disagree with any of these points. It is important to bring them up, however, because having these points explicitly on the table will help them see the significance of the following words from Jeremiah:
Behold, the days come, saith the LORD, that I will perform that good thing which I have promised unto the house of Israel and to the house of Judah. In those days, and at that time, will I cause the Branch of righteousness to grow up unto David; and he shall execute judgment and righteousness in the land. In those days shall Judah be saved, and Jerusalem shall dwell safely: and this is the name wherewith she shall be called, The LORD our righteousness. For thus saith the LORD; David shall never want a man to sit upon the throne of the house of Israel; Neither shall the priests the Levites want a man before me to offer burnt offerings, and to kindle meat offerings, and to do sacrifice continually. And the word of the LORD came unto Jeremiah, saying, Thus saith the LORD; If ye can break my covenant of the day, and my covenant of the night, and that there should not be day and night in their season; Then may also my covenant be broken with David my servant, that he should not have a son to reign upon his throne; and with the Levites the priests, my ministers. As the host of heaven cannot be numbered, neither the sand of the sea measured: so will I multiply the seed of David my servant, and the Levites that minister unto me. Moreover the word of the LORD came to Jeremiah, saying, Considerest thou not what this people have spoken, saying, The two families which the LORD hath chosen, he hath even cast them off? thus they have despised my people, that they should be no more a nation before them. Thus saith the LORD; If my covenant be not with day and night, and if I have not appointed the ordinances of heaven and earth; Then will I cast away the seed of Jacob, and David my servant, so that I will not take any of his seed to be rulers over the seed of Abraham, Isaac, and Jacob: for I will cause their captivity to return, and have mercy on them. Jer 33:14-26
The Mormons claim that Smith the Restoration returned the Aaronic (Levitical) priesthood to the world. But how could it have ever been gone in light of the covenants outlined above?
By contrast, this text is no problem for Catholics, as we believe all the powers and sacrifices of the Levitical priesthood are present in fulfillment in the Catholic priesthood, who have always been present to serve the New David, who is Christ.
