Just keep straight all of us hold some commonalities ... we all believe the 5 solas from the reformation and salvation by faith not works..
The doctrinal difference between Reformed churches is pretty nil ... like the OPC only sing psalms my PCA loves guitars and drums and hymnal and contemporary worship song .. basically we and the OPC , EPC and the BPC all use the same confession of faith.. the Westminster confession ...
Well, until the “reformed” “protestants” start getting Catholic beliefs straight, I don’t think I’ll bother. When people start telling me what I believe, and how wrong I am to believe it, I tend to write them as goofy.
