At that time, a man came to Jesus kneeling and saying: "Teacher, I brought my son to you, for he has a dumb spirit; and wherever it seizes him it dashes him down; and he foams and grinds his teeth and becomes rigid; and I asked your disciples to cast it out, and they were not able." And he answered them, "O faithless generation, how long am I to be with you? How long am I to bear with you? Bring him to me." And they brought the boy to him; and when the spirit saw him, immediately it convulsed the boy, and he fell on the ground and rolled about, foaming at the mouth. And Jesus asked his father, "How long has he had this?" And he said, "From childhood. And it has often cast him into the fire and into the water, to destroy him; but if you can do anything, have pity on us and help us." And Jesus said to him, "If you can! All things are possible to him who believes." Immediately the father of the child cried out and said, "I believe; help my unbelief!" And when Jesus saw that a crowd came running together, he rebuked the unclean spirit, saying to it, "You dumb and deaf spirit, I command you, come out of him, and never enter him again." And after crying out and convulsing him terribly, it came out, and the boy was like a corpse; so that most of them said, "He is dead." But Jesus took him by the hand and lifted him up, and he arose. And when he had entered the house, his disciples asked him privately, "Why could we not cast it out?" And he said to them, "This kind cannot be driven out by anything but prayer and fasting." They went on from there and passed through Galilee. And he would not have any one know it; for he was teaching his disciples, saying to them, "The Son of man will be delivered into the hands of men, and they will kill him; and when he is killed, after three days he will rise."
Τῷ καιρῷ ἐκείνῳ, ἄνθρωπός τις προσῆλθε τῷ Ἰησοῦ λέγων, διδάσκαλε, ἤνεγκα τὸν υἱόν μου πρός σε, ἔχοντα πνεῦμα ἄλαλον. καὶ ὅπου ἂν αὐτὸν καταλάβῃ, ῥήσσει αὐτόν, καὶ ἀφρίζει καὶ τρίζει τοὺς ὀδόντας αὐτοῦ, καὶ ξηραίνεται· καὶ εἶπον τοῖς μαθηταῖς σου ἵνα αὐτὸ ἐκβάλωσι, καὶ οὐκ ἴσχυσαν. ὁ δὲ ἀποκριθεὶς αὐτῷ λέγει· ὦ γενεὰ ἄπιστος, ἕως πότε πρὸς ὑμᾶς ἔσομαι; ἕως πότε ἀνέξομαι ὑμῶν; φέρετε αὐτὸν πρός με. καὶ ἤνεγκαν αὐτὸν πρὸς αὐτόν. καὶ ἰδὼν αὐτὸν εὐθέως τὸ πνεῦμα ἐσπάραξεν αὐτόν, καὶ πεσὼν ἐπὶ τῆς γῆς ἐκυλίετο ἀφρίζων. καὶ ἐπηρώτησε τὸν πατέρα αὐτοῦ· πόσος χρόνος ἐστὶν ὡς τοῦτο γέγονεν αὐτῷ; ὁ δὲ εἶπε· παιδιόθεν. καὶ πολλάκις αὐτὸν καὶ εἰς πῦρ ἔβαλε καὶ εἰς ὕδατα, ἵνα ἀπολέσῃ αὐτόν· ἀλλ᾿ εἴ τι δύνασαι, βοήθησον ἡμῖν σπλαγχνισθεὶς ἐφ᾿ ἡμᾶς. ὁ δὲ ᾿Ιησοῦς εἶπεν αὐτῷ τὸ εἰ δύνασαι πιστεῦσαι, πάντα δυνατὰ τῷ πιστεύοντι. καὶ εὐθέως κράξας ὁ πατὴρ τοῦ παιδίου μετὰ δακρύων ἔλεγε· πιστεύω, κύριε· βοήθει μου τῇ ἀπιστίᾳ. ἰδὼν δὲ ὁ ᾿Ιησοῦς ὅτι ἐπισυντρέχει ὄχλος, ἐπετίμησε τῷ πνεύματι τῷ ἀκαθάρτῳ λέγων αὐτῷ· τὸ πνεῦμα τὸ ἄλαλον καὶ κωφόν, ἐγώ σοι ἐπιτάσσω, ἔξελθε ἐξ αὐτοῦ καὶ μηκέτι εἰσέλθῃς εἰς αὐτόν. καὶ κράξαν καὶ πολλὰ σπαράξαν αὐτὸν ἐξῆλθε, καὶ ἐγένετο ὡσεὶ νεκρός, ὥστε πολλοὺς λέγειν ὅτι ἀπέθανεν. ὁ δὲ ᾿Ιησοῦς κρατήσας αὐτὸν τῆς χειρὸς ἤγειρεν αὐτόν, καὶ ἀνέστη. Καὶ εἰσελθόντα αὐτὸν εἰς οἶκον οἱ μαθηταὶ αὐτοῦ ἐπηρώτων αὐτὸν κατ᾿ ἰδίαν, ὅτι ἡμεῖς οὐκ ἠδυνήθημεν ἐκβαλεῖν αὐτό. καὶ εἶπεν αὐτοῖς· τοῦτο τὸ γένος ἐν οὐδενὶ δύναται ἐξελθεῖν εἰ μὴ ἐν προσευχῇ καὶ νηστείᾳ. Καὶ ἐκεῖθεν ἐξελθόντες παρεπορεύοντο διὰ τῆς Γαλιλαίας, καὶ οὐκ ἤθελεν ἵνα τις γνῷ· ἐδίδασκε γὰρ τοὺς μαθητὰς αὐτοῦ καὶ ἔλεγεν αὐτοῖς ὅτι ὁ υἱὸς τοῦ ἀνθρώπου παραδίδοται εἰς χεῖρας ἀνθρώπων, καὶ ἀποκτενοῦσιν αὐτόν, καὶ ἀποκτανθεὶς τῇ τρίτῃ ἡμέρᾳ ἀναστήσεται.
The memory of this Saint is celebrated on March 30, where his biography may be found. He is celebrated today because his book, The Ladder of Divine Ascent, is a sure guide to the ascetic life, written by a great man of prayer experienced in all forms of the monastic polity; it teaches the seeker after salvation how to lay a sound foundation for his struggles, how to detect and war against each of the passions, how to avoid the snares laid by the demons, and how to rise from the rudimental virtues to the heights of Godlike love and humility. It is held in such high esteem that it is universally read in its entirety in monasteries during the Great Fast.
