There is a case in the Acts of the Apostles where two people lie to the Church, and pretend to donate all of the proceeds from selling their land to the Church and drop dead. This wasn’t because they didn’t give it all, it’s because they publicly gave in front of many others as a show of holiness.

Nope. Acts 5 follows acts 4 (the “But” makes it clear), and acts 4 is all about giving up your riches to live in a commune.

That’s also supported by the teaching that rich people won’t go to heaven (unless you can pass a camel through a needle hole) and James.

Acts 4 along mark 10 are pretty clear that Christians are supposed to give it all and live in a community where “as many as were possessors of lands or houses sold them, and brought the prices of the things that were sold, and laid them at the apostles’ feet: and distribution was made unto each, according as any one had need.”

This is also supported by the teachings that literally states rich people won’t go to heaven (unless they give it away).

So Jesus and early christians were all about living in a commune.

Now, most modern churches come from a roman imperial implementation of an uprising religion at a time where different temple within polytheism were associated with concurring political factions leading to unstability. Christianity was authorized, then chosen as a state religion and accordingly structured. Things branched out from there, becoming a central part of international politics throughout the middle ages, then different flavors of christianity raising from protestanism (which remain globally a minority compared to catholiscism), but they are all structured towards their own goals rather than Jesus’s teachings.
