Is PCA same as Orthdox?
No. Different histories. Going from memory here, so my dates might be wrong. The OPC split from the Northern Presbyterians in 1936, the PCA split from the Southern Presbyterians in 1971. The OPC was originally the "Presbyterian Church in" (or of, I forget) "America". The main church sued over the name, and it became what you see now.
Lemme see....
