If God cared about bricks and morter, he would have built them himself. What has been sanctified and dedicated exclusively to God's service is us. WE are what God cares about, not buildings. We are the ones who need buildings to focus our attention on God. All you have to do to see the cathedrals that God has built is look around you. Look at the Grand Canyon, look at the sunrise, look at a rose. None of these things can be disturbed by noise or guns or foolish people.
We build churches to prove to God how much we charish Him, but he doesn't want or even need the churches. He wants US, and if we need the churches to find him, then that's OK.
Remember, "Where ever there are two or more gathered in My name, there I shall be also".
We should treat churches with reverence, but it's foolish to believe that it matters one whit to God.
I don't think it would be possible for me to disagree with you more strongly. The Lord's teaching regarding the Tabernacle in the wilderness and the building and rebuilding of the Temple shows that he cares a very great deal about the places dedicated to his true worship.
