It is written that we are living stones in God's Temple -- that God lives within us. Christ is the foundation, and Christ is the cornerstone. We are joined together by fellowship, as the mortar which holds us together. It is an expression of love, the work of the Spirit who lives with in us and the outpouring of our own faith.
The leaders of the church were originally chosen from those who were gifted in hospitality (1 Timothy 3:2): they understood the role of fellowship, and how to cultivate it. The more leaders who are gifted in hospitality, the more closely the church holds together in the bond of love. Such church builders are architects who have understood God's love for people and God's vision of us united, understanding each living stone and finding the right place for each. Each stone builds up the whole, and is more secure itself for being joined together. Compare a finished Temple to a pile of rubble, and know: the whole is greater than the sum of the parts.
The "lone ranger" Christians -- the vast numbers of Christians and Christian sympathizers who are unchurched -- are a sign of the problems with love and fellowship in the church. So many people remain apart from the Temple as a solitary stone that has been knocked out of place, and is content to stay there since at least it won't be knocked down again.
As a wise man once said: There is a time to cast away stones, and a time to gather stones together. There is a time for every purpose under heaven. Let our days be days of rebuilding. Let us pray for the architects who would build us together on the foundation of Christ as a Temple of the Spirit.
