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.
