Pelagius, Founder of a Heresy

Pelagius, the founder of a heresy, wrote works of practical value for students before he was declared a heretic: three books On Belief in the Trinity, and one book of Selections from the Holy Scriptures Bearing on the Christian Life. This last was preceded by tables of contents, after the model of Saint Cyprian the martyr. After he was declared a heretic, however, he wrote works bearing on his heresy. [a]
