There is definitely a place for having things in common but it would better to GIVE than to tithe as such.We welcome all who have something to share.
When it comes to roofs on so-called "church buildings" and such, I don't see that the Bible can ever be used in defense of any requirement to support such luxuries, unless maybe one is partaking of that luxury. Otherwise they are free-loaders. Some have tried to point to the temple to defend the idea of "church buildings" being a necessity rather than a luxury, as if that is a legitimate parallel. No. That's a concoction from the imaginations of those who don't see that communal facilities are purely a luxury as opposed to a necessity. Believers can gather in many ways and places without the enormous expense of facilities and all the other trappings.
I suspect that the day is almost upon us when those groupings with facilities, especially those that are tax exempt, will be forced to teach only within the confines of a state sanctioned system of beliefs, such as is happening in Canada right now, and has been going on in China. We need to learn to divorce ourselves from things that can serve as an enslaving boat anchor so that more believers can learn to aspire upward to being a functional Church body that ministers and thrives apart from communal facilities and hirelings. Those things and people are being out-paced by a wicked culture that is more and more becoming intolerant of the Church, and will only embrace those liberal groupings that hold to the same, wicked values as secular culture.
Blessings to you and yours.

Why because, say someone has an extra house, (which amazingly, some people actually DO have) they could use that as a meeting place, rather than ask those who don't have anything to give to tithe from the little they earn.
