2Co_6:16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
1Co_6:19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
Rev 21:22 And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.
The old Jewish sanctuary and the temples were built according to the blueprints God had given, which were made according to the original in heaven. They were instituted by God for a reason and for a time until Jesus came to fulfill all that the sanctuary was all about. No further temples were needed, we have churches --for gathering together to praise God and learn of Him. The original churches were peoples homes and just gathering together outside. For convenience we also have baptisteries---going down to the rivers edge in the middle of winter can be a problem. However, the river was good enough for Jesus. I doubt He considers all these fancy, ornate cathedrals, churches and baptisteries to be necessary. Everything in the sanctuary had a purpose. right down to the color of the threads used to make the veils and curtains--and were specifically for the temple only. A simple container for water for immersion baptism is all that is needed. God is not honored by gold and pearls---the expensive oils used by Mary to anoint His feet were used on Him, not the disciples, nor anyone else. Sorry, but I don't think Jesus would step foot in that baptistery, nor in one of your temples---but then I don't think He's pleased with a lot of these fancy, ornate buildings we call churches. Everything in the early sanctuary and temples pointed to the coming Messiah---He came, we are now His temples, and we are to take care of our own temples and each other looking forward to His second coming to take us home. Everything in this world will be destroyed, and the earth will be made new---none of these things will stand. Every temple, every cathedral, every church, will be gone.
