On the Human Will

St. Maximus the Confessor ca. 580-662

[I]f Adam ate willingly, then the will is the first thing in us that became subject to passion. And since the will is the first thing in us that became subject to passion, if, according to them [the Monothelites], the Word did not assume it along with the nature when He became incarnate, I have not become free from sin. And if I have not become free from sin, I was not saved, since whatever is not assumed is not saved. (Disputatio, 325B)
