Michael Bates makes some interesting points about PCA/PCUSA:
Nearly all of the Presbyterian Churches in Tulsa are a part of the PCUSA. Christ Presbyterian Church is a congregation of the Presbyterian Church in America (PCA). I usually describe it as the Bible-believing Presbyterian denomination (as opposed to the liberal mainline denomination).
While the PCA (which has its General Assembly this week) has its lively theological debates, they are well within the scope of the Westminster Confession, the historic standard of Presbyterian belief. There are 27 overtures on the agenda -- many dealing with presbytery boundaries and committee structure -- but the big theological issue at this year's GA will be whether the Federal Vision / Auburn Avenue / New Perspectives on Paul understanding of covenants and justification are within the bounds of PCA doctrine.
I know a lot of good, devout Christian folk who belong to PCUSA congregations, and there are PCUSA congregations that are, by and large, faithful to the Scriptures. When the northern and southern mainline churches reunited in the early '80s, there was a period in which congregations could withdraw and align with another denomination, without forfeiting their church buildings, which are owned by the denomination, not the individual congregation.
That grace period has long since ended. It would be a huge sacrifice for a congregation to leave the PCUSA, but the level of nonsense seems to grow year after year.
UPDATE: Here is the nonsense in the PCUSA to which he refers:
BIRMINGHAM, Ala. (AP) — The divine Trinity — "Father, Son and Holy Spirit" — could also be known as "Mother, Child and Womb" or "Rock, Redeemer, Friend" at some Presbyterian Church (U.S.A.) services under an action Monday by the church's national assembly.
