Sorry to hear about your friend being deceived by Earl Paulk. This type of thing is happening regularly. A lot of people are being turned off to Yahweh (God) and the Bible because of the antichrist practices of the false churches as mentioned in the podcast.
May be you could turn your friend on to the podcast and recommend he take a deeper look into the Scriptures.
And so the communal sharing model is not going to be very popular in our age of "what's in it for me?"
True, it's not now popular, but I believe it will become so as time goes. People will eventually come to realize it's the only way to live that'll bring about peace, justice and a longer, healthier life.
Early Mormons (on a fairly large scale) tried to live the "law of consecration" but it was ultimately a failure.
The Mormons were not living their communal existence firmly on the Yahweh's laws and Yahshua's teachings. I know for a fact the Mormons don't keep the Holy Days mentioned in
Leviticus 23:1-44. I'm sure there are other laws and teachings they don't follow as well. To be successful it must be done just right. It's not just communal living alone.
