Is Catholicism a False Gospel Like Mormonism?



For me as a committed Protestant, this subject of Catholicism’s theology on the gospel, justification, and works is quite complicated. I’m not going to answer all the questions here, because I’m just not competent enough to do so, and I’d rather be spending my time in other areas I feel more important to my ministry. So please offer me some grace even if you disagree with my conclusions. If you want more competent authorities on the matter, here are a handful of sources:

1) Norm Geisler and Ralph MacKenzie’s Roman Catholics and Evangelicals, and Geisler's recent statement in The Evangelical Dictionary of World Religions: "These doctrinal similarities are too strong to place a non-Christian label on the essential doctrines of official Roman Catholicism" ("Roman Catholicism," [Baker, 2018], 434)

2) Ken Samples, “Is the Catholic Church Christian?” and “Is Catholicism a Cult?" (Ken said in the former reference “that the majority of evangelical Protestant theologians and scholars who are knowledgeable concerning Catholicism would be perplexed to hear Catholicism classified simply as a ‘non-Christian religion’ or an ‘anti-Christian cult.’”)

3) Francis Beckwith’s Return to Rome (written by a former top evangelical apologist and a former president of the Evangelical Theological Society, who went back to his Catholic roots)

4) The original and late Bible Answer man, and author of The Kingdom of the Cults, Walter Martin, also held that Catholicism wasn’t a cult or heretical to the extent that it would qualify as "non-Christian" even though he certainly had problems with it. See The Christian Research Institute (CRI) statement below, which was issued 8 months prior to Martin's death. Even after his debate on The John Ankerberg Show against Father Mitch Pacwa, SJ, Martin (according to his daughter Jill) regarded him as a brother in Christ. Further, Martin had Pacwa on the editorial board of The Christian Research Journal and had him, among other ordained clergy, lay hands on Martin in his Southern Baptist ordination (Beckwith, Op. cit., 42-3). Such would be impossible if Martin knew Pacwa’s doctrines were damnable heresy. I used to go to Martin’s Sunday school class while in college, I used to regularly listen to him on The Bible Answer Man Program, and I would attend a number of his lectures. In fact, I was looking forward to being his intern at CRI for the fall semester of 1989 when he suddenly died in June of that year. The phrase “Catholic, Protestant, and Orthodox” was continuously used by him to bring the weight of the authority of the historical Church against any heresy. Perhaps long before I knew him Martin was more disparaging of Catholicism. Nonetheless, the Roman Catholic Church was never included in his standard textbook of the cults—The Kingdom of the Cults.

5) Also, the new General Editor for that book, the well-known Christian apologist Ravi Zacharias, with the endorsement of Martin's family, has continued to keep Roman Catholicism out of it. When asked specifically, Zacharias wouldn't label Catholicism as a cult.

6) Evangelical religious scholar, Rob Bowman, has referred to Catholicism as a Christian denomination and a major stream of "historic Christianity" in a very narrow sense (Jesus' Resurrection and Joseph's Visions: Examining the Foundations of Christianity and Mormonism, 13-5).  

7) Even the greatest Christian apologist today, William Lane Craig, has stated that Catholicism is part of "Mere Christianity." This also could not be the case if these Craig understood Catholicism to be in fact teaching a false gospel.

Catholicism and Mormonism

I don’t find Catholicism identical to what LDS teach on the matter at hand, viz., that one is only made right with God only after doing all one can do (i.e., personal perfection). There is no initial justification for LDS that offers complete forgiveness and eternal life, and as the late LDS President Spencer W. Kimball taught,

"Trying is [n]ot [s]ufficient [n]or is repentance complete when one merely tries to abandon sin. To try with a weakness of attitude and effort is to assure failure in the face of Satan’s strong counteracting efforts. What is needed is resolute action. 

…This connection between effort and the repentance which attracts the Lord’s forgiveness is often not understood.

…[Concerning the woman caught in adultery,] [t]here seems to be no evidence of forgiveness. His command to her was, ‘Go and sin no more.’ He was directing the sinful woman to go her way, abandon her evil life, commit no more sin, transform her life. He ways saying, Go, woman, and start your repentance; and he was indicating to her the beginning step – to abandon her transgressions.

…[W]hen she had done these things the forgiveness of the Savior could overshadow her and claim her and give her peace.

…The Lord cannot save men in their sins but only from their sins, and that only when they have shown true repentance” (The Miracle of Forgiveness, 164-6). 

Furthermore, in LDS categories, Christ didn’t even die for all sins since some sins are not forgivable (e.g., killing and subsequent offenses of adultery in D&C 42, and also LDS leaders’ past teaching on one’s own blood atonement for certain grievous sins). This all is certainly something Catholicism would doctrinally disagree.

Catholicism and Protestantism 

Protestantism, quite unlike Mormonism, never claims to be a restoration. Rather, Protestantism is a reformation movement birthed out of the Roman Catholic Church. If Catholicism denied one or more of the essential doctrines of the Christian Faith, then it would be a cult and not part of the true Church. A genuine restoration would be required. Nonetheless, such was not the case. Given the theological problems of the 16th century, a genuine reformation was required. 


The subject turns on the role of works in Catholic theology. Do those works invalidate the true gospel making it a false gospel or is the true gospel simply packaged in a way that is confusing to the hearer? There’s a real important difference here.   

It reminds me of the Positive Confession speakers’ claim that we are begotten gods. Walter Martin made the controversial claim that these guys are still Christians. Robert Bowman in his article on various views of deification says that the Positive Confession view is not easily classified. These Positive Confession speakers clearly affirm monotheism, and yet they speak in such a convoluted way. 

For the average individuals untrained in theology, even cases of orthodox Christian deification are such that they conclude advocates of such a position must be polytheists and outside the Christian doctrine of monotheism. Yet, whether it is Positive Confession speakers or orthodox theologians who teach deification, all steadfastly affirm monotheism and adamantly decry polytheism. Yes, we have problems understanding what they are talking about since prima facie it seems so contradictory. However, it’s not really fair to be so dismissive of these people given the parameters they’ve already clearly articulated. In situations like this, if we have a hard time really understanding what’s being taught, then it’s better to use the principle of charity and give the benefit of the doubt to such people until we come to see how there really is no contradiction in their minds. And this seems especially true when most evangelical Protestant theologians and scholars hold Catholicism to be classified as genuinely “Christian.”  

There is a fundamental problem with the Protestant mind when it comes to thinking in the Catholic categories of justification. Catholics conflate the clear distinction that Protestants have made between justification and sanctification. The Council of Trent put it this way: “[J]ustification itself, which is not only a remission of sins but also the sanctification and renewal of the inward man through the voluntary reception of the grace and gifts whereby an unjust man becomes just and from being an enemy becomes a friend, that he may be an heir according to hope of life everlasting” (Chapter VII). Catholics teach a difference between initial justification and justification that ought to follow throughout one’s life. The former is what Protestants typically mean by “justification.” The other justification for Catholics is a matter of staying justified by works.

Now if a Protestant objects that this latter type of justification is not about works, then they would not simply be objecting to Catholicism, but to many other branches of Protestantism as well. The objecting Protestant (typically one of a more Reformed bent) would also have to conclude that these other branches of Protestantism are outside of Christianity and preaching a false gospel. That’s a pretty hard pill to swallow. These other branches of Protestantism affirm that performing works of righteousness may be freely abdicated after our conversion, and thus, one’s salvation may be lost. In fact, since most Protestant denominations are not Calvinistic, most Protestants hold that one may lose one's salvation. The basic historic position of the Church prior to the Reformation was that an individual may lose one's salvation by losing faith and thereby discontinuing to obey our Lord and following His commands. Nonetheless, all denominations of the Faith once for all delivered to the saints are all Christians who affirm the true gospel that our salvation for all our sins is ultimately given as a gift from God through the sacrifice of His Son.

The Council of Trent in chapter IX is clear that none of us can be absolutely certain that any of us have received the forgiveness of sins.  After all, Paul did say to test ourselves to see whether we are in the faith (2 Cor. 13:5). As a result, chapter X talks about being further justified by one’s “faith co-operating with good works.” One of the arguments given here is James 2:24: “Do you see that by works a man is justified, and not by faith only.” So continued justification is just as biblical as what the Protestants mean by “sanctification.” Then in chapter XI it goes on to talk about how Jesus taught that if we love Him, then we keep His commandments (Jn. 14:15). Earlier Jesus ties belief with obedience when He says, “He who believes in the Son has eternal life; but he who does not obey the Son will not see life, but the wrath of God abides on him” (Jn. 3:36). John is clear in his epistle that we know that we love Jesus if we keep His commands, and if we say we love Him and don’t keep His commands, then we’re liars (1 Jn. 2:3-4). Hence, “the necessity” of keeping His commands. 

There is nothing that a Protestant should disagree with here per se. Of course and again, a certain type of more Reformed Calvinistic Protestant may object to an understanding of this necessity of keeping the commands implying a losing of one’s initial justification if the commands are not followed, but as Trent stated the issue above, it is all biblical and every Protestant should uphold that.     

At this point a Protestant may object by saying that Catholics are still teaching a false gospel, since the initial justification is dependent on baptismal regeneration whether that be for an adult or an infant, and belief is certainly ruled out for the latter. However, again one would have to exclude various Protestant denominations that hold to the same means of initial justification. Again, a pretty hard pill to swallow. Certainly the nature of belief is up for debate here and is a secondary issue to the nature of the gospel itself, viz., that Christ paid for all our sins, He resurrected, and invites sinners to currently live in His kingdom by learning to live life as He would live (cf. Mat. 4:23 and 1 Cor. 15:1-5). Such debates on the nature of belief have to do with how individual beliefs arise in a context of community. Nonetheless, there is no passage of scripture that explicitly says that not getting the right answer here lands one in hell.


Speaking of hell, the final issue I’ll address concerns the issue of “anathema” the Catholic Church has offered from the Council of Trent in reaction to Protestantism. Canon 30, for example, says, “If anyone says that after the reception of the grace of justification the guilt is so remitted and the debt of eternal punishment so blotted out to every repentant sinner, that no debt of temporal punishment remains to be discharged either in this world or in purgatory before the gates of heaven can be opened, let him be anathema.” Is this the gospel and does this entail that those who reject this are cursed of God and not saved being that they are outside the Church of Christ?  

Even if that is what is meant by anathema, this is no reason to hold that this entails a false gospel. Believers who have received the grace of justification may still have to be punished by God for their own transgressions, because “whom the Lord loves, He also chastens” (Heb. 12:6). David had imputed righteousness apart from works (Rom. 4:4-8), but the Lord still chastened him in taking his son who was the product of adultery. Whether the Lord metes out punishment in this life or the next prior to entering paradise, what real difference does it make? Even though I take it that the Bible never says anything about a temporary punishment for believers after this life, that doesn’t entail such could not be the case. To conclude this would be based on an argument from silence, and that is fallacious.

Regardless of this point, it’s been argued that the literal meaning of anathema is not what is to be understood from the judgment of a Church council. There was no intention of a permanent damnation to hell. The Lonely Pilgrim notes, “When the councils pronounced holders of a doctrine anathema, it marked a formal excommunication from the Church: nothing more and nothing less." He argues that if there was a connotation of permanent damnation, then the missionary efforts to Protestants by the Jesuits wouldn’t make much sense. Further, he argues that if there is a problem here, it’s specifically for those who rebel against the judgments of their church. There is no general relevancy to all Protestants today. He says, “You can’t very well be excommunicated from something you were never formally a part of.”      

Now even if the The Lonely Pilgrim is wrong on all this, I don’t see why a group of believers being hyper-exclusionary of one’s judgments marks them as “false Christians” or “heretics,” who teach a false gospel and land them in hell anyway. I don’t see the chapter and verse on that either, and again, we can easily think of other Protestant Christian groups who act in this way.

"RC is a false religious system. They deny the sufficiency of Christ's death on the cross by teaching and performing the mass multiple times a day all over the world. In the mass it is said that the priest has the power to bring Christ down out of heaven for an "unbloody" sacrifice. RC's are taught that they must eat and drink the bread and wine for salvation - that the elements truly are the actual body and blood of Christ. Christ Jesus' once for all sacrifice is denied in these teachings. The pope is given the names that are used for the Triniity: holy father (in scripture used only for God by Christ Himself), the alter Christus, and head of the church. It uses man's teachings alongside the Bible, it adds works to salvation, and denies many true teachings of biblical Christianity. In these way it is like other false religious systems like Mormonism. This is only the tip of the iceberg of all that is false in RC. See for more info." (10/17/16)

"Also would like to add that contained in every Roman Catholic "altar" is the relic of a dead saint:

In the case of John Paul II, the Vatican is teaching that his blood has special power. Housed in an elaborate reliquary, some of the blood of John Paul, collected during medical tests while he was alive and subsequently preserved, was held aloft for the worship of the crowd. The container of blood was prominently displayed during the beatification Mass, and was kissed by Pope Benedict XVI and other worshipping priests.

Such macabre idolatry is common Vatican practice. In order to be consecrated for service, every altar of a Roman Catholic church must contain such a relic of some dead "saint". The Roman Catholic church holds tens of thousands of body parts, and containers of bodily fluids of the dead, in its collection of so-called relics of the saints. These include what are alleged to be the hair and breast milk of Mary the mother of Jesus, pieces of John the Baptist's head, and Peter's brain and teeth. All are worshipped by the Catholic faithful. John Calvin mentions all of these and many more horrors in his Treatise on Relics. Revulsion against the worship of such relics was also a significant factor in Martin Luther's break with Rome.
