This number 318, which Pope St. Leo calls mysterious, has been adopted by most of the fathers of the church. St. Ambrose assures us that the number of 318 bishops was a proof of the presence of our Lord Jesus Christ in his Council of Nicæa, because the cross designates three hundred, and the name of Jesus eighteen. St. Hilary, in his defence of the word _consubstantial_, approved in the Council of Nice, though condemned fifty-five years before in the Council of Antioch, reasons thus: "Eighty bishops rejected the word _consubstantial_, but three hundred and eighteen have received it. Now this latter number seems to me a sacred number, for if is that of the men who accompanied Abraham, when, after his victory over the impious kings, he was blessed by him who is the type of the eternal priesthood." And Selden relates that Dorotheus, metropolitan of Monembasis, said there were precisely three hundred and eighteen fathers at this council, because three hundred and eighteen years had elapsed since the incarnation. All chronologists place this council in the year 325 of our modern era; but Dorotheus deducts seven years, to make his comparison complete; this, however, is a mere trifle. Besides, it was not until the Council of Lestines, in 743, that the years began to be counted from the incarnation of Jesus. Dionysius the Less had imagined this epoch in his solar cycle of the year 526, and Bede had made use of it in his "Ecclesiastical History." It will not be a subject of astonishment that Constantine adopted the opinion of the three hundred or three hundred and eighteen bishops who held the divinity of Jesus, when it is borne in mind that Eusebius of Nicomedia, one of the principal leaders of the Arian party, had been an accomplice in the cruelty of Licinius, in the massacres of the bishops, and the persecutions of the Christians. Of this the emperor himself accuses him, in the private letter which he wrote to the church of Nicomedia: "He sent spies about me," says he, "in the troubles, and did everything but take up arms for the tyrant. I have proofs of this from the priests and deacons of his train, whom I took. During the Council of Nicæa, with what eagerness and what impudence he maintained, against the testimony of his conscience, the error exploded on every side! repeatedly imploring my protection, lest, being convicted of so great a crime, he should lose his dignity. He shamefully circumvented and took me by surprise, and carried everything as he chose. Again, see what has been done but lately by him and Theogenes."
