In theory, all supposed “Christians” who considered themselves “based” are in agreement with he above statement.
In practice, not a single Protestant actually lives by it.
If Christianity is true, then it necessarily means that a loving God who is the epitome of Truth, Love, Mercy, and… JUSTICE, has, necessarily MUST have, very clear and defined rules as to what is and is not good. And thus what is acceptable or not acceptable behaviour. This is why the Catholic Church and actual catholics have always maintained that outside of the Catholic Church there is no salvation. And that non-Catholics are not in fact Christians at all, but heretics.
This is also absolutely obvious and true regarding anything that is true. It either is true, just and correct, or it is not. Just as in math, the tiniest deviation from the truth will eventually lead to untenable errors and collapse.
Since the Catholic Church was there from the very start, with Popes and everything else, it necessarily MUST follow that EITHER the Christian God exists and therefore Catholicism MUST be true, and indeed infallible, OR the Christian God does not exist and all of Christianity is a lie.
Furthermore, we can tell that if the Christian God is real and True, then His Church MUST be infallible, that is, the official pronouncements of it must also be TRUE. And while any number of men and women within it can be in abysmal error, or even part of the enemy forces, the overall official position of His Church cannot be flawed. A Perfect God cannot create or allow an imperfect Church to exist on Earth. While He can and does allow imperfect humans (because Free Will) His Church will be supernaturally protected from error.
And this has indeed been the case with the Catholic Church, which has all of its rules written down in the Code of Canon Law of 1917 plus whatever Papal encyclicals were released up to 9th October 1958 when the last valid Pope died. Everything since has been the work of Satanists, infiltrated into the Church for at least 200 years and creators of the Satanic and Heretical abomination that is Vatican II.
The only people still holding to the truth and the official position of the Catholic Church are Sedevacantists.
Because tolerating evil, lies and fakeness is NOT part of Christianity and only Catholics are Christians, this is why Catholics do not pray with non-Catholics or consider their “Churches” as valid or relevant.
And in most cases the protestants get really upset about it, yet it is an obvious way to be.
It’s why I always make the analogy of how much sewage to you want in your ice cream.
The truth is ONE.
It is infallible. It is eternal. It is not open to corruption.
And the truth itself remains what it is regardless of what you feel about it. Just like God Himself.
So, if you are not a Sedevacantist Catholic yet, you may want to ask yourself why that is. What, exactly, is your position that you think it somehow can avoid these inescapable logical conclusions? Because there is absolutely not a single logical argument against what I have written here. In fact, the only objection I have ever heard worth mentioning at all, from even the most intelligent Protestants is simply this:
“I feel that…” And fill in the blanks. Well, I have news for you. Some people “feel that” they should be of a sex different than the one they were born as. And yet, surgically mutilating yourself doesn’t change the fact you will remain the sex you were born as, for the entirety of the rest of your life.
This is much the same. It really doesn’t matter how you feel about it. Maths is a thing. Reason and logic are a thing. The Truth is a thing. Your feelings about any of the above? They are not a thing to anyone anywhere except you.
