This tenet was held by the Manichæans and other heretics, and is traced back to the Apostolic age by Bishop Pearson (Exposition of the Creed, Art. i. p. 79, note c).  Compare Athanasius c. Apollinarium, I. 21; II. 8; c. Gentes, § 6; de Incarnatione, § 2, in this series, and Augustine (c. Faustum, xx. 15, 21, and xxi. 4).
