true children only. Therefore the Lord spoke in parables to those who could not hear: but to the Disciples he explained the parables in private: for the brightness of the glory is for those who have been enlightened, the blinding for them that believe not.” These mysteries, which the Church now explains to thee who art passing out of the class of Catechumens, it is not the custom to explain to heathen. For to a heathen we do not explain the mysteries concerning Father, Son, and Holy Ghost, nor before Catechumens do we speak plainly of the mysteries: but many things we often speak in a veiled way, that the believers who know may understand, and they who know not may get no hurt.
