It can be no matter of surprise to us that, in a persecution which threatened all classes of society, there should have been many who, when they were accused of being Christians, wanted the courage to undergo the pains of martyrdom, and escaped the punishment by joining in a pagan sacrifice. When the storm was blown over, these men again asked to be received into the Church, and their conduct gave rise to the very same quarrel that had divided the Christians in the reign of Decius. Meletius, a bishop of the Thebaid, was at the head of the party who would make no allowance for the weakness of their brethren, and who refused to grant to the repentant the forgiveness that they asked for. He had himself borne the same trials without bending, he had been sent as a criminal to work in the Egyptian mines, and had returned to Alexandria from his banishment, proud of his sufferings and furious against those who had escaped through cowardice. But the larger part of the bishops were of a more forgiving nature; they could not all boast of the same constancy, and the repentant Christians were re-admitted into communion with the faithful, while the followers of Meletius were branded with the name of heretics. In Alexandria, Meletius soon found another and, as it proved, a more memorable occasion for the display of his zeal. He has the unenviable honour of being the author of the great Arian quarrel, by accusing of heresy Arius, at that time a presbyter of the church of Baucala near Alexandria, and by calling upon Alexander, the bishop, to inquire into his belief, and to condemn it if found unsound. Arius frankly and openly acknowledged his opinions: he thought Jesus a created being, and would speak of him in no higher terms than those used in the New Testament and Apostles' Creed, and defended his opinions by an appeal to the Scriptures. But he soon found that his defence was thought weak, and, without waiting to be condemned, he withdrew before the storm to Palestine, where he remained till summoned before the council of Nicaea in the coming reign. It was during these reigns of trouble, about which history is sadly silent, when Greek learning was sinking, and after the country had been for a year or two in the power of the Syrians, that the worship of Mithra was brought into Alexandria, where superstitious ceremonies and philosophical subtleties were equally welcome. Mithra was the Persian god of the sun; and in the system of two gods, one good and the other wicked, he was the god of goodness. [Illustration: 179.jpg SYMBOL OF MITHRA] The chief symbol in his worship was the figure of a young hero in Phrygian cap and trousers, mounted on a sinking bull, and stabbing it in sacrifice to the god. In a deserted part of Alexandria, called the Mithrium, his rites were celebrated among ruins and rubbish; and his ignorant followers were as ignorantly accused of there slaying their fellow-citizens on his altars.
