The problem stems from a misunderstanding of "church". Church is not a building. Church is not a membership roll. Church is "ekklesia", the "called-out ones". It is the Body of Christ, and we each are individual members. Yes, there is a special anointing when Christians gather, and thank God for it, but when we leave the building, or the gathering if there is no building, we do not stop being the church. We are the church, wherever we are.
Or at least we're supposed to be. As I wrote to you in an earlier thread, in the West church membership has historically conferred social benefits. Even to this day, candidates for high office suddenly tend to get vocal about it. Thus at times it attracts people for the wrong reasons. But it is exactly the opposite in Communist and Muslim nations, where Christianity brings persecution rather than opens doors. And I do mean persecution. There, it takes sincere commitment be become a Christian, because the cost is so high. And while they have to take care to their walk among the unbelievers for wisdom's sake, they know that they have not stopped being Christians, and that at any moment they may be called into account for it. See the youtube series, The Cross in China, for a picture of what that looks like.
There is a lot of misunderstanding about the church, even among Christians, even among some here. Somehow the church became buildings, cathedrals, rituals and high church office, to say nothing about internecine warfare over doctrinal minutia. But it's all about "Christ in you, the hope of glory". The early church was big on the truth that "God does not dwell in houses made with hands". It's what got the first martyr, Stephen, killed. And when Jesus defined the church, He intentionally reduced it to the least possible plurality of "two or more gathered together in My name". We are the church, and that does not change when we leave the building.
