The principle common to these and other like heretics (who ignored or misconstrued many passages of Scripture which plainly declare the completeness and truth of our Lord’s humanity) was that matter is inherently and by its very nature evil. Mani, therefore, and the rest were easily led to think shame of attributing to Christ a real, tangible, visible body. For the doctrines of Mani, see note on I. 57. Valentinus was a Gnostic, who lived at Rome (whither he came from Alexandria) between 140 and 160 a.d. Marcion became known as a heresiarch in the papacy of Eleutherius (177–190 a.d.). For the doctrines of Valentinus and Marcion, see Robertson’s Church History, Bk. I. ch. iv.
