A little background - I was raised in liberal Presbyterianism, was awakened through Evangelicalism / Fundamentalism, and then trained-up by Reformed theology... The first phase of my Reformed training was a result of imbibing anything published by Banner of Truth, or written by John Gerstner, RC Sproul, Francis Schaeffer, Lorraine Boettner, AW Pink, etc... And then -
In my mid-twenties I was happily existing in a quasi-sectarian Reformed groove when the men's group at my church decided to memorize the Nicene Creed. I immediately fell in love with its simplicity, depth, and biblical cadences. Some months later I was earnestly reading my latest issue of Tabletalk - which was doing an extended critique of Eastern Orthodoxy. One of the articles simultaneously acknowledged that the dogmatic foundation of EO theology is the Nicene Creed, yet went on to viciously criticize EO as an idolatrous sect.
WHAM! All of a sudden my tidy conceptual universe was shaken. It was the closest thing to an out-of-body experience I had ever had. How could we call people who whole-heartedly affirm the Trinitarian Gospel according to the Nicene Creed (which is a short-hand summary of the teachings of Scripture) heretics simply because they weren't iconoclastic Protestants? Even if I disagreed with much of EO theology (which I do) surely we must be loathe to dismiss them as crass idolaters! And if that is true for EO's, how much more true is that for Christians of all orthodox / catholic traditions!
Now of course, I realize that you can affirm something and de facto strangle it and trample it with stupid and stubborn errors. I get that. I am not naive. However, how could such a crassly idolatrous sect produce such a profound Christian as Fyodor Dostoevsky - or even Alexander Schmemann? Where is the Fyodor Dostoevsky of Reformedom? Why haven't we produced him? And we are we so sectarian if we are the true defenders of GRACE? I don't get that. I have Reformed convictions, but surely these do not mix well with a sect spirit. (Do they?)
