the question or op is 'Did Jesus actually start a church to himself?'
Scripture is pretty explicit in it's proof texts. He commissioned the apostles to go baptizing in his name [or, also the name of the Father, the Son and the Holy Ghost]. He laid out instructions on what the apostles should do, what they should teach and how to live. Of course he started a church to himself.
Ask yourself this. If you read that Mohamed said he started a church to himself, would you state something like ' the koran was written 100 years after he died and he was speaking in future tense...so...'
Of course not. The reason is because the argument is not reasonable. Don;t take that as a dig, it's just that you would never read that and think 'he didn;t start a church to himself' even though the test says that he did.
Your argument that HE DIDN"T start his church is not within reason.
Make sense?
Just asking
I'm going to build a house here. Therefore the house already exists.
That's your argument TTWYSF. Can you not see why it doesn't even work in itself, and without the surrounding context of the other writings accepted as canon which paint a different picture?
A Jewish man does Jewish things, says a few nice things, constantly references Jewish scripture, but also claims to be divine. His followers are Jews who do Jewish things, constantly reference Jewish scripture, and think the Jewish man is the Jewish messiah who'll return after death to smite Jewish foes. A reasonable interpretation of events during the life of the Jewish man may just well be that this is a bit Jewish.
Vanderhoven gives an interpretation which fits with the evidence, such as it is from the canon texts. Early believers were into personal salvation, not a church. There's a lot of support for that view of very early christianity where there is little in the way of a central authority to establish doctrine. Where doctrine can be changed by personal divine revelation.
It's not that I don't understand what you're attempting to argue, it's that it's an argument unsupported by even the most selective use of the evidence available.
