+Jn 17: 20-26
“I pray not only for them, but also for those who will believe in me through their word,
so that they may all be one, as you, Father, are in me and I in you, that they also may be in us, that the world may believe that you sent me.
And I have given them the glory you gave me, so that they may be one, as we are one,
I in them and you in me, that they may be brought to perfection as one, that the world may know that you sent me, and that you loved them even as you loved me.
Father, they are your gift to me. I wish that where I am they also may be with me, that they may see my glory that you gave me, because you loved me before the foundation of the world.
Righteous Father, the world also does not know you, but I know you, and they know that you sent me.
I made known to them your name and I will make it known, that the love with which you loved me may be in them and I in them.”

The Prayer of the Hour of Jesus
2746 When “his hour” came, Jesus prayed to the Father. His prayer, the longest transmitted by the Gospel, embraces the whole economy of creation and salvation, as well as his death and Resurrection. The prayer of the Hour of Jesus always remains his own, just as his Passover “once for all” remains ever present in the liturgy of his Church.
2747 Christian Tradition rightly calls this prayer the “priestly” prayer of Jesus. It is the prayer of our high priest, inseparable from his sacrifice, from his passing over (Passover) to the Father to whom he is wholly “consecrated.”
2748 In this Paschal and sacrificial prayer, everything is recapitulated in Christ: God and the world; the Word and the flesh; eternal life and time; the love that hands itself over and the sin that betrays it; the disciples present and those who will believe in him by their word; humiliation and glory. It is the prayer of unity.
2749 Jesus fulfilled the work of the Father completely; his prayer, like his sacrifice, extends until the end of time. The prayer of this hour fills the end-times and carries them toward their consummation. Jesus, the Son to whom the Father has given all things, has given himself wholly back to the Father, yet expresses himself with a sovereign freedom by virtue of the power the Father has given him over all flesh. The Son, who made himself Servant, is Lord, the Pantocrator. Our high priest who prays for us is also the one who prays in us and the God who hears our prayer.
2750 By entering into the holy name of the Lord Jesus we can accept, from within, the prayer he teaches us: “Our Father!” His priestly prayer fulfills, from within, the great petitions of the Lord’s Prayer: concern for the Father’s name; passionate zeal for his kingdom (glory); the accomplishment of the will of the Father, of his plan of salvation; and deliverance from evil.
2751 Finally, in this prayer Jesus reveals and gives to us the “knowledge,” inseparably one, of the Father and of the Son, which is the very mystery of the life of prayer.
Saint Justin, also known as Justin Martyr (Greek: Ιουστίνος ο Μάρτυρας, Latin: Iustinus Martyr) was an early Christian apologist, and is regarded as the foremost interpreter of the theory of the Logos in the 2nd century. He was martyred, alongside some of his students, and is considered a saint by the Roman Catholic Church, the Anglican Church, the Eastern Orthodox Church, and the Oriental Orthodox Churches.
Most of his works are lost, but two apologies and a dialogue did survive. The First Apology, his most well known text, passionately defends the morality of the Christian life, and provides various ethical and philosophical arguments to convince the Roman emperor, Antoninus, to abandon the persecution of the fledgling sect. Further, he also indicates, as St Augustine did regarding the “true religion” that predated Christianity, that the “seeds of Christianity” (manifestations of the Logos acting in history) actually predated Christ’s incarnation. This notion allows him to claim many historical Greek philosophers (including Socrates and Plato), in whose works he was well studied, as unknowing Christians.
Justin Martyr was born at Flavia Neapolis (today Nablus) in Samaria into a pagan family, and defined himself as a Gentile. His grandfather, Bacchius, had a Greek name, while his father, Priscus, bore a Latin name, which has led to speculations that his ancestors may have settled in Neapolis soon after its establishment or that they were descended from a Roman “diplomatic” community that had been sent there.
In the opening of the Dialogue, Justin describes his early education, stating that his initial studies left him unsatisfied due to their failure to provide a belief system that would afford theological and metaphysical inspiration to their young pupil. He says he tried first the school of a Stoic philosopher, who was unable to explain God’s being to him. He then attended a Peripatetic philosopher but was put off because the philosopher was too eager for his fee. Then he went to hear a Pythagorean philosopher who demanded that he first learn music, astronomy, and geometry, which he did not wish to do. Subsequently, he adopted Platonism after encountering a Platonist thinker who had recently settled in his city.
And the perception of immaterial things quite overpowered me, and the contemplation of ideas furnished my mind with wings, so that in a little while I supposed that I had become wise; and such was my stupidity, I expected forthwith to look upon God, for this is the end of Plato’s philosophy.
Some time afterwards, he chanced upon an old man, possibly a Syrian Christian, in the vicinity of the seashore, who engaged him in a dialogue about God and spoke of the testimony of the prophets as being more reliable than the reasoning of philosophers.
There existed, long before this time, certain men more ancient than all those who are esteemed philosophers, both righteous and beloved by God, who spoke by the Divine Spirit, and foretold events which would take place, and which are now taking place. They are called prophets. These alone both saw and announced the truth to men, neither reverencing nor fearing any man, not influenced by a desire for glory, but speaking those things alone which they saw and which they heard, being filled with the Holy Spirit. Their writings are still extant, and he who has read them is very much helped in his knowledge of the beginning and end of things, and of those matters which the philosopher ought to know, provided he has believed them. For they did not use demonstration in their treatises, seeing that they were witnesses to the truth above all demonstration, and worthy of belief; and those events which have happened, and those which are happening, compel you to assent to the utterances made by them, although, indeed, they were entitled to credit on account of the miracles which they performed, since they both glorified the Creator, the God and Father of all things, and proclaimed His Son, the Christ [sent] by Him: which, indeed, the false prophets, who are filled with the lying unclean spirit, neither have done nor do, but venture to work certain wonderful deeds for the purpose of astonishing men, and glorify the spirits and demons of error. But pray that, above all things, the gates of light may be opened to you; for these things cannot be perceived or understood by all, but only by the man to whom God and His Christ have imparted wisdom.
Moved by the aged man’s argument, Justin renounced both his former religious faith and his philosophical background, choosing instead to re-dedicate his life to the service of the Divine. His newfound convictions were only bolstered by the ascetic lives of the early Christians and the heroic example of the martyrs, whose piety convinced him of the moral and spiritual superiority of Christian doctrine. As a result, he thenceforth decided that the only option for him was to travel throughout the land, spreading the knowledge of Christianity as the “true philosophy.” His conversion is commonly assumed to have taken place at Ephesus though it may have occurred anywhere on the road from Judaea to Rome.
