i see what you're saying, cardero. and as someone else pointed out, the thing with meeting in houses is that those meeting places will often get too small for a congregation. the number of believers will grow, and the community will seek the building of a house of worship where they may go specifically to worship and congregate. it's the whole idea of a sacred space. which could be argued around if one supposes that no one place is less or more holy than another. yet there is something in the human nature which tends towards longing for a home-space. whether a nation, homeland, house, or temple. it is a way we can draw closer to one another, use our creativity and skill to build a place that reflects something of the magificence we understand God to be, something of His grandness and wonder, and it is a way to gather in His name. if one is so inclined.
