Right. And they weren't Baptists either. And, as you have noticed in reading them and I agree with you, most of them would have a hard time recognizing us as fellow believers.
I may have overlooked someone but the only example I have seen on here of someone against penal substitution and possibly a modern Baptist was on a website that is well known as being very liberal. And I'm not referring to politics so much as theology. The guy who had the article in Christianity Today, Thomas McCall, was at Trinity Evangelical Divinity School and I don't think that is Baptist. Wright, is he a Baptist? Are there any Baptist churches that really refute PSA?
Now I have from the Mennonite website, a paper on the Atonement and they admit themselves that Anabaptists are all over the place, many times did not explain themselves in systematic form and the writer claimed some had a view very similar to PSA.
Direction: The Atonement in Anabaptist Theology
I have a lot of sympathy for Mennonites, being partially raised in a United Missionary Church and I used to have Amish neighbors and have looked into their theology. But the modern Mennonite church, is indeed often "liberal".
What I think happens and why this is important is that from the days of the liberal movement to critique scripture as being unreliable there is always a pull for such folks to get away from views that might seem primitive or that don't fit the modern image of God they have created. They want to make Christianity an ethical system without the baggage of people going to hell or there being a necessity of blood sacrifices. They especially want to avoid people having to give an account to God for their sin so naturally, any view of the atonement that emphasizes collective salvation and minimized the idea of sin being an offense to God would be attractive. Now that does not mean that everyone who disagrees with PSA is automatically thinking along those lines but I am still asking - where are serious, solid, theologically conservative Baptist clergymen who truly dislike PSA?
