The Church is unified through communion and the ecumenical creeds. You Baptists are "Christian" to the extent that you confirm the statements of the ecumenical creeds. Most of you reword most of the creedal statements in your humanly devised "statements of faith." Seems silly that you must "re-invent the wheel" in every local congregation.
You all do have communion, don't you?
there is NO organizational "Church" on the earth, but there are saints iof it in evry church building/group....
