Do you disagree? That the church building is not to be set apart and sanctified as a holy place?
Examples? Every old testament reference to the holiness of the tabernacle. Nadab and Abihu offering the unclean fire. Eli's two worthless sons profaning the temple and priests. Christ himself driving the money changers out of the temple for turing it into a place of commerce.
If you're content with your church building being some sort of club-house for worldliness - that's on you. We treat ours differently. The gathering of believers is to be a thing of worship, awe, and reverence - giving the LORD His glory and honor. Not satisfying the fleshly desires of the unsaved.
There's no such thing as a carnal Christian.
Now if you wouldn't mind, could show me some scripture where "the Church" has become "a place?"
"There's no such thing as a carnal Christian."
Paul seems to disagree in his letters to the church at Rome (romans 17) and to the church at Corinth (1 Cor. 3).
"That the church building is not to be set apart and sanctified as a holy place?"
It is the people who are set apart and sanctified. The building is just that. When we are raptured it will still be here. Some meet in schools, some in shopping centers, some in Masonic Halls some in even meet in KOC buildings. Where two or three are together in His name there is He, even in a bar.
