Claim: During the Synod of Milan in 389 Augustine created "On the Good of Marriage", written in opposition to the heresy of Jovinian, who held differing views on marriage.
Evidence: Augustine's "On the Good of Marriage" was written against somewhat that still remained of the heresy of Jovinian. He mentions this error in b. ii. c. 23, de Nuptiis et Conc. Jovinianus, he says, who a few years since tried to found a new heresy, said that the Catholics favored the Manichæans, because in opposition to him they preferred holy Virginity to Marriage.
