I have a feeling there may be errors in my premise or conclusion, but here goes...
I have thought about the possibility that when Jesus basically gave Peter the keys to heaven, yes I think it's symbolic, that Peter went on to found Catholicism.
When I presented this theory to someone one time, they basically said, to paraphrase: "I fathom you may be right. But other Christianity existed, as Paul founded churches." I think they eventually made the case that Paul's churches were kind of like the Protestanism of today had Protestantism existed back then.
So here's the curveball I present. A couple of people on this forum say that Paul was crazy and not inspired. In doing so, are they unintentionally and indirectly making the argument, if my argument is correct, that if you choose Christianity, the true path is pretty much, more or less Catholicism?
None of the above actually......according to Bible prophesy, Jesus and his apostles warned about a coming apostasy....a falling away from the truth taught by Christ.
In his parable of the "wheat and the weeds" Jesus said that the devil would sow fake "wheat" in the same field as Jesus had sown fine wheat. The illustration makes perfect sense if you understand what seed it was that the devil sowed. In Bible times there was a toxic weed named "bearded darnel" sometimes called "wheat's evil twin".
Wheat's Evil Twin Has Been Intoxicating Humans For Centuries
It mimics wheat in the early growing period, but as the harvest approaches the two take on different characteristics. Then the reapers can go out and remove the weeds before the final harvest.
In the days of the apostles there was already some who wanted to deviate from the truth....the apostles whilst they were alive acted as a restraint for this apostate thinking...but after the apostles passed away, the apostasy gained ground....doing what "weeds" do best.
Paul warned that Jesus would not come again unless this apostasy took place first. (2 Thessalonians 2:3) He speaks about the restraining influence of the living apostles....
"And now you know what is acting as a restraint, so that he will be revealed in his own due time. 7 True, the mystery of this lawlessness is already at work, but only until the one who is right now acting as a restraint is out of the way."
Once the apostles passed away there was nothing to stop the rot setting in.....Christendom was born with Roman Catholicism and its reign of bloodshed and torture proves that Jesus Christ was never in it.
Where was the love Jesus promoted? A love even of one's enemies? (Matthew 5:44-45)
"By their fruits" Jesus said we would recognize his true disciples.....by the love they had for one another. (John 13:34-35)
So neither Catholicism nor Protestantism is genuine Christianity....all teach the same errors....things that Christ never taught.
1) That Jesus is God and part of a triune godhead.
2 That humans have an immortal soul that departs from the body at death.
3) That God punishes the wicked in a blazing fire for all eternity.
None of those things are found in ancient Judaism or in early Christians teaching.
According to Daniel, it was not going to be until "the time of the end" that there would be a cleansing and refining of people. (Daniel 12:9-10) These processes require the removal of stains or impurities....and Christendom was full of them. Those who refused the cleansing would understand nothing.
Jesus' words at the judgment say it all.....
“Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter. 22 Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness.’" (Matthew 7:21-23 NASB)
Notice that Jesus is rejecting those who claim him as their "Lord" but he says outright that he "never knew" these ones......"NEVER" means "not ever".....let that sink in for a moment. He is calling these 'fake Christians' those who "practice lawlessness". These are the weeds sown by the devil who were only going to be identified at "the time of the end" when Jesus would sent out his reapers to harvest the weeds first and throw them in the oven to destroy them completely. Then he will gather the wheat into his storehouse. (Matthew 13:24-30; 36-43; Revelation 18:4-8)
That, I believe, is how the Bible explains it.
