No doubt, Catholics will say, “But we do have truth and sound doctrine. In fact, it is only the Catholic Church who has the ‘fullness of the truth’ (CCC #819).”
But not only does the Catholic Church not have the sound doctrine and “fullness of truth” that it claims to have (as this blog and many other websites attest), but it doesn’t even have the level of unity that it claims for itself. See here:
Interestingly, the Catholic Church’s idea of “unity” also includes union with Protestants (for example, the dangerous and unbiblical “Evangelicals and Catholics Together” document) and also union with pagan and demonic world religions, as well. See here:
We are here warning everyone that this same false unity will also be used by the “man of sin,” the “son of perdition” (2 Thessalonians 2:3), also known as the antichrist, to form his ungodly one-world church (Revelation 13:7-8, 12). We can only hope and pray that this thought is just as disturbing to others as it is to us. You see, this craving for unity at any cost is very dangerous.
Having a single “authoritative” human authority over the church does not guarantee truth, just as a single ultimate authority over the U.S. Constitution does not guarantee that the right thing will be done. An ultimate human authority can become corrupt. This same “ultimate authority” over the Constitution has produced evil things like the Roe v. Wade decision on abortion, which regrettably, became the law of the land. In the same way, having a person (pope) over the entire church does not guarantee truth or righteousness, either.
But the Catholic will say, “But, unlike the judges who interpret the Constitution, the pope is infallible!” Then why try to use the Constitution argument in the first place, since it is a false analogy? So, now they must admit that the Constitution argument is an invalid “apples and oranges” comparison, and the resulting mismatch negates this whole argument.
So, the bottom line on this unity issue is this - you can either:
1) Accept the fact that there are always going to be differences / disagreements in Bible interpretation, (yet with imperfect, but acceptable, levels of unity in different places) or
2) You can default and let someone else “infallibly” decide what Scripture says, like a church whose “unity” is an all-inclusive tolerance for false doctrine, or a dictator-type church with its forced unity.
This second type of “unity” does not work, and neither does the “Constitution” argument.
