So when did we start to go to church? I don't really want to malign Constantine, but a lot of stuff sorta' began to go awry when he came on the scene in the early 300s. The beautiful cathedrals were originally designed as an expression of the glory of the Lord. (I have seen many of them in Europe and they are amazingly beautiful) Over time though, people began to conceive that the building was where the Lord was. The more a person entrusts their knowledge of spiritual things solely to others, the more they lose the reality of the Lord's active presence. And so, you have to go somewhere else to find him.
We love coming together to worship. The scriptures encourage us to do so. But we try not to "go to church" We try to "be" the church.
