You might find this fascinating, or you might find it depressing: a family tree showing where our denomination, the Presbyterian Church in America (PCA) fits. You may not have known that Rev. Paul Settle, only recently retired from our staff a few years back, was instrumental in humbly overseeing the formation of the PCA. If this piques your interest, the bookstore has at least a few summaries of how the PCA came to be.
THANKS for this diagram. This gives better context to our current stage in the grand drama of church history.
