My prayers are with you. I was once an elder in a PCUSA church and gained visibility into the workings. Radicals have taken over the denomination and they are not guided by God.
I left, which was hard but I felt it was the only choice I had.
In the PC(USA) church property is owned by the Presbytery (group of geographically close churches) but is managed by the local Session (governing board). This is well documented in the bylaws of the PC(USA). Regardless of whether you approve of it or not it is the governing law of the denomination - a denomination that is structured on democratic principles. Granted the PC(USA) - of which I am a member - is quickly losing population because of the liberal direction taken at the national level. But many small-town churches remain the bedrock of conservative society. The mega-churches have to many votes to overcome on the national (General Assembly) level. Remember that King George II called the American Revolution the Presbyterian Revolution - 13 signers of the Declaration were Presbyterians. There is hope for us yet!
