I was thinking about this subject lately, and I never saw it in February for some reason.....
But wasn't the early church still learning how to do things? Weren't they trying to work out exactly what their purpose was on earth, and how they were supposed to best accomplish it? That's why all the Epistles were written, to teach them just what they were supposed to be doing.
I mean, I hear these conversations about "house churches".....it's said that that's how the NT church met, and so why do we have buildings today? Well, if you think about it, most of our churches start out as house churches, too. We just grow out of the house and get a church building eventually. How do we know that the early church didn't do the same thing? Well they did. They found rooms that would hold them all.......
I would never say to do anything the Bible says is wrong, and I'd never say go against any Bible principles. But things like where they met, or even how many elders they had, and what they called their elders, and how big their congregations grew.....I don't think any of that was set as a command. Alot of it is the development of a church that at first thought Christ was coming back any minute and they wouldn't be here long, then later realized they had better start planning for the long-term while looking for a "short-term return" of Christ.
