I was doing some research to a question a student had for me and I came upon this really interesting article...
I learned a connection I hadn't made before from this article. I've heard about the argument about the name of Peter but never had an evangelical argue with me about it personally. But, I'd never thought that, if Matthew was originally written in Aramaic, intended to evangelize an predominately Aramaic-speaking group of Jews, it makes sense that the point evangelicals are making is moot. It also makes sense that 1 John and Paul, two authors that are very theologically distinct in terms of style, both use the Aramaic version of Peter's name, Kephas/Cephas.
Peter really is the rock on which God built his church. It just gets more convincing all the time.
