Jerome

Epistle CVII

ad Laetam:

When a few years ago your relative Graecus, whose name bespeaks his noble birth, held the office of prefect of the city, did he not utterly destroy the cave of Mithras with all the monstrous crew that give names to teh initiates in their grades, the crow, the gryphon, the soldier, the lion, the Persian, Heliodromus, and father? These his works were pledges as it were sent forward, whereby he gained Christian baptism.

Adversus Jovinianum

I. 7:

According to the popular legend Mithras and Erichthonius were born in a rock or in the ground by the unaided passion of lust.

Adversus Jovinianum

II. 14:

Eubulus the author of a history of Mithras in many volumes states that there are three classes of Magi among the Persians, the first of which, men pre-eminent in learning and eloquence, confine their food to pulse and vegetables alone.

Comm. in Amos

V: 9-10:

Basilides gives to the omnipotent god the uncouth name of Abraxas, and asserts that according to the Greek letters and the number of the cycle of the year this is comprehended in the Sun's orbit. The name Mithra, which the Gentiles use, gives the same sum with different letters.
