Could the teachings of Meister Eckhart on the total extinguishing of the will and its replacement by God’s be a kind of “blowback” from the fact that the controversy over monothelitism was apparently never fully understood in the West? It’s especially telling that monothelitism is apparently not among the heresies of which he was accused. Perhaps this, rather than the filioque, is the issue that really separates East and West.
People make fun of it as a minor heresy, but monothelitism packs a punch.
