No one should even be going to "church", Christ warned us quite a few times about going to those "unrighteous assemblies", those "dens of thieves"... He encouraged us to gather and fellowship in open areas or near rivers, lakes, or seas, even in our own private homes.
God encouraged us to tithe, to bring our first fruits to the storehouse, Christ taught us that the storehouse is no longer a building, but is within the temple which is our bodies and the storehouse is within our hearts. So in a sense, God was teaching us how to save.
Paul, writing on behalf of not only himself but all the apostles, declared that to be yoked together with unbelievers was to receive the grace of God in vain. The remedy, he said, was to come out from among the unclean to perfect holiness in the fear of the Lord. Perfecting holiness requires us to live in community. Living in community requires oversight. For that purpose, he taught how to recognize overseers. Peter wrote that the ones who were true elders should take the oversight.
Take the oversight. Assume it. Create a New Covenant community. For men, they should learn to be a sons, first. Then, they should learn to be brothers. At some point, they may be required to learn how to be husbands; and, then, fathers. Eventually, every Christian man who learns to be good neighbor (having the supporting testimony of those who know him) should become an elder taking oversight of the flock of the Lord.
I wouldn't be surprised to find out, some day, that the monasteries and abbeys and friaries of the Orthodox churches are - though they seem nothing more than vestigial remnants of religious tradition - communities that reflect something of the first expression of Christianity.
Paul said that if he built up what God tore down, it would be a disgrace to God. Being that Christ tore down the temple and built it up in us, our body. It then becomes apparent that such buildings are a disgrace to God, and God calls His people to come out and depart from them.
Christ did not come to bring peace, but a sword... He came to cause separation, but in this time, it's apparent that all the unrighteous assemblies are worried more of unifying all relgions.
Agreed. Community is all the "temple" we need. We are the body of Christ. We know that our body - the one Body into which we have all been placed - is the temple.
