In 2006, Trevin Wax posted two interviews: one with an evangelical who left for Eastern Orthodoxy, and another individual who left Eastern Orthodoxy for evangelicalism. The two interviews are quite informative and worth reading. He then posts a comparison, contrasting the two expressions of faith.
Trevin correctly identifies the reformation doctrine of "sola scriptura" as the principal dividing line between Evangelicals and adherents of Eastern Orthodoxy.
Theron’s testimony should serve as a warning to Baptists who toy with the doctrine of sola Scriptura. Without Scripture as the final authority, Theron is right. One has to find another authority. Unfortunately, most of the people that reject sola Scriptura do not find their authority in the Roman Catholic or Orthodox Church. They prop themselves up as the authority and head down the road of Protestant Liberalism. When sola Scriptura goes, it’s a “fast track” in most cases to liberalism.
