The PCA keeps coming up short (the OPC is not even on radar).
Remember Craig Barnes, president of Princeton Theological Seminary? Here was how he stood in opposition to the PCA at the time that women objected to Tim Keller receiving the Kuyper Prize:
Our seminary embraces full inclusion for ordained leadership of the church. We clearly stand in prophetic opposition to the PCA and many other Christian denominations that do not extend the full exercise of Spirit filled gifts for women or those of various sexual orientations. We know that many have been hurt by being excluded from ministry, and we have worked hard to be an affirming place of preparation for service to the church.
I wonder which prophets Dr. Barnes goes to to oppose the PCA. But at least it’s an ethos.
Now comes a Yale Divinity School graduate and PCUSA pastor who puts the differences between the PCUSA and PCA this way:
I am a Presbyterian (PCUSA) pastor who has family members who attend PCA (Presbyterian Church of America) churches. The best (and simplest) way to differentiate between the two is that the PCA asserts that the Bible is inerrant, or without error. The PCUSA believes that the Bible is authoritative, or guided by God, but actually written by human beings, influenced by their culture, time, and limited knowledge of the world.
You might not notice this while visiting either churches, except that the PCA, because of their stance on the Bible, read Paul’s writings that prohibit women from participating in the leadership of worship as what God intended. So you will not see a female pastor (like myself) at a PCA church, or indeed, any women ruling elders (the governing body within each congregation).
The order of worship for both denominations is essentially the same; both are part of the Reformed movement. However, the preaching will likely be quite different, with a PCUSA pastor emphasizing the broad love of God for all of God’s people, and a PCA pastor leaning more towards evangelism and conversion.
No mention of the alt-right, Confederate Monuments, or even LBGT. Maybe the lesson is that resolutions are overrated.
