Where do the gospels and Acts say that He didn't?
Which proves my point. If the biblical penmen didn't leave any kind of historical record of this point of Jesus' model, then it doesn't matter. The church as we practice it today is a far cry from the one Jesus modeled that was recorded.
It seems to me they had large crowds gathering more than weekly for awhile...to be taught!
You still haven't shown from biblical record where there were "weekly" meetings with the same individuals. Besides, though some did want to hear Him teach (sometimes to "prove" His alleged heresy), many came because of His reputation for performing miracles and He took advantage of the situation to speak to them. There is no evidence He met with the same group of hundreds of people at the same location, the same time each week.
Peter preached in Acts and 3000 were saved. Again,in Acts, 5000 men were saved.
So these 8000 people were meeting weekly for singing, offering, announcements, preaching, invitation, perhaps baptism or Lord's Supper and leaving after two hours? Though I can't prove they didn't meet, again, there is no record so even if true, it would have been of no importance.
Acts 6, they called the entire congregation together for an organizational meeting.
Wait, why did they have to be called? Why not address the issues after their weekly church service?
Jesus is the founder and foundation for the church, but He choose to start it in Acts...with the Jews.
So Jesus in Matthew 18 had clearly established church discipline for an organization (or spiritual organism) that didn't exist yet. Actually, it sounds like it was something in which they were already participating. He certainly never put the church in this passage in futuristic terms.
If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
He also chose to scatter the church thru persecution in Acts 7-8...to further His plan to expand His church.
Finally something I agree with you about.
Later Paul expanded the church into all the world, and preached to large crowds as well as smaller groups.
Though he did do
some church planting, some of the churches he addressed were already in existence meaning Christianity had already spread.
There is nothing more spiritual or biblical about a small group model than a large congregation/small group model.
Absolutely nothing!
Spiritual? Perhaps not. Biblical? Since there is no record of weekly assemblies as we do today, I would say "not biblical". Again, that doesn't mean "anti-biblical" but rather a non issue. Besides, how often does your church include meals as a part of their "church service"?
