I was raised Presbyterian (PCUSA), and one of the problems I had with religion was that too often churches strayed from the biblical to the secular world view. When I was 18 I attended a Baptist Church (Southern Baptist Convention) and accepted Christ as my personal savior. I alternated between different protestant denominations for several years but always held to scripture as my guiding star. If it wasn’t in Scripture, it wasn’t true. The Presybterians (PCUSA) came up short, as did the Methodists. The Baptists so far have not dissappointed me. I now attend a small Baptist church. Always check you church against Scripture. If they don’t agree, accept what the Bible says. ALWAYS! If the church you are attending comes up short, LEAVE IT! It is an apostate church.
While there are a few good PCUSA churches left, the safest thing is to avoid that denomination completely. For Presbyterians, I’d recommend the OPC, the ARP, or the PCA.
