Heresies to others, they were of course orthodox in their own eyes

Christ was the Son of God. All agreed. But what was the Nature of Christ? The subtle Alexandrian intellect asked this question about the year 300, and the Arian heresy was the result. It asked it again about 400 and produced the Monophysite heresy. And a third query about 600 produced a third heresy, the Monothelite. Let us glance at these three in turn. Heresies to others, they were of course orthodox in their own eyes. Each believed itself the only interpreter of the link that binds God to Man.
