The church is the body of believers with Christ as the head...no matter what denomination or place of worship. That church. As for phoning it...I would recommend a conversation with the head of that church...He is certainly willing and able, and most importantly always available to answer questions you might have...His word never fails us in that respect.
“......no matter what denomination or place of worship. “
Really? The “Reverend” Wright meets your definition? The “Reverend” Vicki Eugene Robinson does? How ecumenical of you! An embrace of racism and sodomy. Not very Christian though.
