Our Lord Jesus Christ has appointed certain men to be guides and teachers of the world and stewards of his divine mysteries. Now he bids them to shine out like lamps and to cast out their light not only over the land of the Jews but over every country under the sun and over people scattered in all directions and settled in distant lands. That man has spoken truly who said: No one takes honor upon himself, except the one who is called by God, for it was our Lord Jesus Christ who called his own disciples before all others to a most glorious apostolate. These holy men became the pillar and mainstay of the truth, and Jesus said that he was sending them just as the Father had sent him.

“And when it was day, He called His disciples to Himself; and from them He chose twelve, whom He also named apostles.” (Lk 6: 13)

Our Lord Jesus Christ spent the night in prayer, conversing with His Father and God in heaven in a way indescribable and beyond our powers of understanding, a way which is solely known to Himself. He thus makes Himself an example to us of that which is necessary for salvation, for He taught us in what way we too may rightly and blamelessly offer our prayers. He then came down from the mountain, and appointed those who were to be the world’s teachers, according to the words He spoke, “You are the light of the world.” (Matt. 5: 14) Of this appointment of the holy Apostles, the blessed David also makes mention addressing himself, as it were to Christ, “You shall make them princes in all the earth; I will make Your name to be remembered in every generation.” (Ps. 45:16) For truly, while they were in the body, they make mention of the glory of Christ, telling His mystery both in cities and villages. Now that they have been called to the mansions that are above, they still converse with us about Him, by the most wise history which they have written concerning Him.
