If Christians are a spiritual temple why would this be necessary?
Deuteronomy 12:11-14 "then to the place that the Lord your God will choose, to make his name dwell there, there you shall bring all that I command you: your burnt offerings and your sacrifices, your tithes and the contribution that you present, and all your finest vow offerings that you vow to the Lord. 12 And you shall rejoice before the Lord your God, you and your sons and your daughters, your male servants and your female servants, and the Levite that is within your towns, since he has no portion or inheritance with you. 13 Take care that you do not offer your burnt offerings at any place that you see, 14 but at the place that the Lord will choose in one of your tribes, there you shall offer your burnt offerings, and there you shall do all that I am commanding you.
It seems to me to build or set-up another place goes against the commandment of God. He's already placed His name INSIDE us, a spiritual temple. There's not need, nor commandment for a physical structure.
Just my thought on the matter.
