“The Reformers combated the Renaissance philosophers and later modern philosophers, who were forced to give up their attempt to find a universal to reconcile man and God. They were forced to give up because they allowed things like secular humanism, existentialism, and rationalism to enter their models. It was the Roman Catholics who supported this growing humanism!
For example, the Catholics were pushing the idea of an incomplete Fall, thus leaving man with an autonomous intellect. The Renaissance philosophers LOVED THIS! The Reformers, OTOH, held to the Biblical view of a complete Fall. They said that only God was autonomous. The next 500 years have sadly led us to where we are today in modern philosophy. A philosophy with no absolutes that is controlled by relativism. Again, the Reformers were the ones who fought against this.”
And then, of course, there are we Orthodox, doing and believing the same things for 2000 years. How do the reformers account for, or better said, dismiss us, FK?
Oh, I wouldn't use the word "dismiss". :) We're still all Christians after all. I will say that I think that Orthodoxy is harder to pin down, so I could understand why a Protestant who was of the mind converting to Orthodoxy instead of Roman Catholicism. Less historical baggage.
I think a list of important differences between Orthodoxy and Reformed theology would have to start with justification by faith versus theosis. That has to be a big one. From there we could move on to things like original sin, general sin, grace, regeneration, election, atonement, God's sovereignty, and especially Biblical inerrancy and Biblical worth. (There are of course others.) So, while I do really respect that the Orthodox have been more consistent for a longer time, I do not equate that with necessarily being correct. As Kosta has indirectly noted, many generations of Jews were wrong for at least as long as the Orthodox believe they have been right. :)
