The idea of the Mediator comes to us from Persia, and the title was borne by Mithra before it was ascribed to Christ.  Zoroaster taught that there was existence itself, the unknown, the eternal, “Zeruane Akerne,” “time without bounds.”  From this issued Ormuzd, the good, the light, the creator of all.  Opposite to Ormuzd is Ahriman, the bad, the dark, the deformer of all.  Between these two great deities comes Mithra, the Mediator, who is the Reconciler of all things to God, who is one with Ormuzd, although distinct from him.  Mithra, as we have seen, is the Sun in the sign of the Bull, exactly parallel to Jesus, the Sun in the sign of the Lamb, both the one and the other being symbolised by that sign of the zodiac in which the sun was at the spring equinox of his supposed date.  “Mithras is spiritual light contending with spiritual darkness, and through his labours the kingdom of darkness shall be lit with heaven’s own light; the Eternal will receive all things back into his favour, the world will be redeemed to God.  The impure are to be purified, and the evil made good, through the mediation of Mithras, the reconciler of Ormuzd and Ahriman.  Mithras is the Good, his name is Love.  In relation to the Eternal he is the source of grace, in relation to man he is the life-giver and mediator.  He brings the ‘Word,’ as Brahma brings the Vedas, from the mouth of the Eternal. (See Plutarch ’De Isid. et Osirid.;’ also Dr. Hyde’s ‘De Religione Vet.  Pers.,’ ch. 22; see also ‘Essay on Pantheism,’ by Rev. J. Hunt.) It was just prior to the return of the Jews from living among the people who were dominated by these ideas, that the splendid chapter of Isaiah (xl.), or indeed the series of chapters which form the closing portion of the book, were written:  ’Comfort ye, comfort ye my people, saith your God.  Prepare ye the way of the Lord, make straight in the desert a highway for our God.  Every valley shall be exalted, and every mountain and hill shall be made low, and the crooked shall be made straight, and the rough places plain.’  And then follows a magnificent description of the greatness and supremacy of God, and this is followed by chapters which tell of a Messiah, or conquering prince, who will redeem the nation from its enemies, and restore them to the light of the divine favour, and which predict a millennium, a golden age of purified and glorified humanity.  It is thus manifest that the inspiration of these writings came to the Jewish people from their contact with the religious thought of the Persians, and not from any supernatural source.  From this time the Jews began to hold worthier ideas concerning God, and to cherish expectations of a golden age, a kingdom of heaven, which the Messiah, who was to be the sent messenger of God, should inaugurate.  And this kingdom was to be a kingdom of righteousness, a day of marvellous light, a rule under which all evil and darkness were to perish” ("Plato, Philo, and Paul,” Rev. J.W.  Lake, pp. 15, l6.)
