The Divine Institutions, in seven books, establishes the Christian religion by refuting false religion or paganism, treating about the origin of error, of false wisdom, then of true wisdom and religion, of justice, of true worship and of happiness. Lactantius converted to Christianity, a religion persecuted by the Roman Empire, causing him to exile, returning during a edict of toleration. The other matters of which he treats is of the work of God and the wrath of God.
