5. If, however, what I have stated be insufficient to convince any one that the prophets were sent from one and the same Father, from whom also our Lord was sent, let such a one, opening the mouth of his heart, and calling upon the Master, Christ Jesus the Lord, listen to Him when He says, “The kingdom of heaven is like unto a king who made a marriage for his son, and he sent forth his servants to call them who were bidden to the marriage.” And when they would not obey, He goes on to say, “Again he sent other servants, saying, Tell them that are bidden, Come ye, I have prepared my dinner; my oxen and all the fatlings are killed, and everything is ready; come unto the wedding. But they made light of it, and went their way, some to their farm, and others to their merchandize; but the remnant took his servants, and some they treated despitefully, while others they slew. But when the king heard this, he was wroth, and sent his armies and destroyed these murderers, and burned up their city, and said to his servants, The wedding is indeed ready, but they which were bidden were not worthy. Go out therefore into the highways, and as many as ye shall find, gather in to the marriage. So the servants went out, and collected together as many as they found, bad and good, and the wedding was furnished with guests. But when the king came in to see the guests, he saw there a man not having on a wedding garment; and he said unto him, Friend, how camest thou hither, not having on a wedding garment? But he was speechless. Then said the king to his servants, Take him away, hand and foot, and cast him into outer darkness: there shall be weeping and gnashing of teeth. For many are called, but few are chosen.” Now, by these words of His, does the Lord clearly show all [these points, viz.,] that there is one King and Lord, the Father of all, of whom He had previously said, “Neither shalt thou swear by Jerusalem, for it is the city of the great King;” and that He had from the beginning prepared the marriage for His Son, and used, with the utmost kindness, to call, by the instrumentality of His servants, the men of the former dispensation to the wedding feast; and when they would not obey, He still invited them by sending out other servants, yet that even then they did not obey Him, but even stoned and slew those who brought them the message of invitation. He accordingly sent forth His armies and destroyed them, and burned down their city; but He called together from all the highways, that is, from all nations, [guests] to the marriage feast of His Son, as also He says by Jeremiah: “I have sent also unto you my servants the prophets to say, Return ye now, every man, from his very evil way, and amend your doings.” And again He says by the same prophet: “I have also sent unto you my servants the prophets throughout the day and before the light; yet they did not obey me, nor incline their ears unto me. And thou shall speak this word to them: This is a people that obeyeth not the voice of the Lord, nor receiveth correction; faith has perished from their mouth.” The Lord, therefore, who has called us everywhere by the apostles, is He who called those of old by the prophets, as appears by the words of the Lord; and although they preached to various nations, the prophets were not from one God, and the apostles from another; but, [proceeding] from one and the same, some of them announced the Lord, others preached the Father, and others again foretold the advent of the Son of God, while yet others declared Him as already present to those who then were afar off.
