Indeed the church belongs to God, and He builds it.
Who is to say but what it is now is what God built? It helps maintain perspective to think of it this way. If it is a Baptist church, and you a member, how would you feel if an Assembly of God person joined it, then decided it needed to be transitioned to an AoG church?
Many of those in traditional churches have chosen to be there for theological reasons, not personal preference in music. Do they not have the right to worship as the Holy Spirit is leading them?
I don't mean to be crass, but it really does come across as stealing a building sometimes. If someone strongly believes a church must change that much from what it is to survive, why not start another church? Why come in speaking as though unless the church changes it somehow doesn't care about the lost or will just up and die? And if those things are true, why not let it die? And start another church? I've watched this happen, and am watching it literally kill two local churches right now. Yes, they will probably die. The buildings will be for sale for a song. And the newbies will gobble them up for "new starts." In a third case, the newbies came in and instead of starting a new, different style work, joined an established one. With enough new members to overwhelm the one's that built the building, it went elder rule, total change in theology as well as music, and the one's who built it were "disciplined" out the door.
All perfectly legal. Nice building they stole, by the way. Now the one's that built the physical plant either worship at home or other churches.
And the town views the one's currently in the building as having no integrity.
Wow. Very sad.
