with EVERYTHING in the Fathers, then YOU SHOULDN'T QUOTE THEM.
Well, I think that's problematic.
There is NO COMMUNION that agrees with everything in the Fathers. And that's not surprising, is it?
But there is a rather tiresome tendency on the part of some to insist that Lutherans just have no business with them at all, and that when we point out what they say, we are invariably "taking them out of context" - by which they mean more than ignoring the context of a given writing, but instead ignoring the context of the Fathers' lives. The assumption of these folks is that the Fathers were Orthodox or Catholic (in the sense of what those jurisdictions currently teach).
But that is to assume a priori what the very appeal to the Father's writings was intended to examine. When the Lutherans read the Fathers they heard and saw in them things that didn't actually FIT with the teaching and practice of the Roman Church in their day. They found at many points the Fathers could be witnesses to an understanding of the Sacred Scriptures that could correct and help renew the Church, and which they recognized as utterly congruent with the conclusions they had themselves drawn from Scripture.
As a Lutheran I do not grant the premise that "we are NOT the Church of the Fathers." Rather, the exact opposite. We regard St. Augustine as a father in the faith, so too St. John Chrysostom, so too St. Irenaeus, and so on and on. And here's the key: we treat them no differently than we treat Dr. Luther or Dr. Walther. Do we subscribe to everything Luther said about anything? Was he never wrong? No, of course not!
I've been hammered for inviting personal judgment, but I'll risk it yet one more time. Folks, don't buy into the Roman or Orthodox assumption that the Fathers are THEIRS. Do some reading on your own. You'll find some odd things; some things you wonder how they could have thought that; and some things that will delight and amaze you. They are not infallible and they never pretend to be and surprise, surprise! They even tell you to disregard what they say if they don't show you what they teach from the Scripture. Fancy that!
I've personally read from them every day for years; they've done anything but persuade me that the Orthodox and Rome have the corner on them. I think that just as the Lutheran Church is strengthened by learning from them, so too the Roman and Orthodox Christian would be. And all of them will find things that they disagree with, but pondering over what the Fathers pass on is a profitable exercise for any Christian. Sasse: "A Church without patristics is just a sect." Amen!
P.S. If you're Roman or Orthodox, you REALLY don't need to write to tell me how I've got this all wrong. We already know you think that. :)
