However, the OPC website also says this:
“The Orthodox Presbyterian Church stands in the line of what are commonly called the Ecumenical Creeds: the Apostles’ Creed, the Nicene Creed, and the Creed formulated at the Council of Chalcedon. The Reformation was not a departure from these Creeds so much as a return to them. For example, the Heidelberg Catechism (which has always been honored by Presbyterian and Reformed believers) is in large part a restatement of the Apostles’ Creed according to its original meaning. And other Reformed Creeds, Catechisms, and Confessions do much the same thing. They restate the faith enshrined in the Ecumenical Creeds in such a way as to exclude error and misunderstanding.”

You beat me to the punch, sir. No doubt the good Dr. E. has a suitable explanation forthcoming and has not left town under the cloak of night.
