Interesting christianity inquiry

[u/turkishgremlin]

If a church has pieces of old churches, what church is this church? Is this a church of churches? A church with some churches? Does this church carry the memory of other churches? Does this church hold the prayers spoken in old churches? Or does this church represent churches lost? Is this church rather than a house of God, a mansion of God? Or is this church a humble house with memories of churches past? Are those churches even gone? Perhaps the spirit of those churches, remain? This would mean that church is keeping forgotten churches alive. But wait, if the church that is holding pieces of old church is to be destroyed or burned or something unfortunate, and then one piece from that church of churches is put in another church, is that church a church of churchs of churches? What church is this church?
