Note 2 — Chapter IX
Reading edition
Alcuin (ibid., i. sec. 13) also answers: "If Christ be the adopted Son of God, because as man, he could not be of God's substance: then must he also be Mary's adopted son in respect to his Deity. But then Mary cannot be the mother of God." But this Alcuin thinks an impious conclusion. Cp. also Contra Felic., vii. sec. 2.
