The timing of the arrest and the Passover
On the third Sabbath, when the light shines, they seize the Christ, in which time they also anticipate and complete the Passover. Thus, they defile the Passover with them by moving it toward evening on the twelfth day, two days before the Passover, while the light is shining, calculating the night into the day—that is, from Tuesday to the fourth Sabbath. Consequently, the church observes these four days because of the seizure of the Lord, fasting throughout the entire year except only during Pentecost and the Epiphanies.
Having been seized toward evening when the light shines, he remains in the court of Caiaphas the whole night. For do not suppose that he was seized toward evening on the fifth day; read the Gospel according to John and examine it, and you will see that when he is seized from Gethsemane, he is brought to Caiaphas. He remained in the house of Caiaphas until morning. In the morning, he is handed over to Pontius Pilate; and this occurred on the fourth of the Sabbaths. He spends that day before Pontius Pilate and the night until morning.
On the fifth of the Sabbaths, he is sent to Herod, who was then in Jerusalem, because he himself had also come with the others to eat the Passover. As that man questioned him many things and, not being deemed worthy of an answer, sends him back to Pilate, he remained until the ninth hour, having been shut up in the praetorium. And a certain betrayal ran forth, saying, even until our own times,

τρίτῃ σαββάτων ἐπιφωσκούσης τετράδος συλλαμβάνουσι τὸν Χριστόν, ἐν ᾗ καὶ τὸ πάσχα προλαμβάνοντες ἐπετέλουν. 206 βεβρώκει τοίνυν μετ' αὐτῶν τὸ πάσχα πρὸς ἑσπέραν τῇ δωδεκάτῃ πρὸ δύο ἡμερῶν τοῦ πάσχα, ἐπιφωσκούσης ιγ, λογιζομένης τῆς νυκτὸς εἰς τὴν ἡμέραν τουτέστιν ἀπὸ τρίτης εἰς τετράδα σαββάτων· ὅθεν ἡ ἐκκλησία τὴν τετράδα φυλάττει διὰ τὴν τοῦ κυρίου σύλληψιν, νηστεύουσα δι' ὅλου τοῦ ἔτους πάρεξ μόνον πεντηκοστῆς καὶ ἐπιφανίων. Συλληφθεὶς δὲ πρὸς ἑσπέραν ἐπιφωσκούσης τετράδος μένει ἐν τῇ αὐλῇ τοῦ Καιάφα ὅλην τὴν νύκτα. μὴ γὰρ νόμιζε ἐν τῇ πέμπτῃ πρὸς ἑσπέραν αὐτὸν συνειλῆφθαι, ἀνάγνωθι εἰς τὸ κατὰ Ἰωάννην εὐαγγέλιον καὶ διάσκεψαι καὶ ὁρᾷς, ὅτι ὅτε μὲν ἀπὸ Γεθσημανῆ συλλαμβάνεται πρὸς Καιάφαν φέρεται. ἔμεινεν δὲ ἐν τῇ οἰκίᾳ τοῦ Καιάφα ἕως τῆς ἕω. πρωίας δὲ παραδίδοται Ποντίῳ Πιλάτῳ· γέγονε δὲ τοῦτο τετάρτῃ τῶν σαββάτων. καὶ ποιεῖ τὴν ἡμέραν ἐκείνην παρὰ Ποντίῳ Πιλάτῳ καὶ τὴν νύκτα ἕως πρωΐ. πέμπτῃ δὲ σαββάτων ἀποστέλλεται πρὸς Ἡρῴδην, ὄντα τότε ἐν Ἱεροσολύμοις, διὰ τὸ καὶ αὐτὸν ἐληλυθέναι μετὰ τῶν ἄλλων φαγεῖν τὸ πάσχα. καὶ ὡς ἐκεῖνος πολλὰ αὐτὸν ἐρωτήσας καὶ μὴ καταξιωθεὶς ἀποκρίσεως ἀντιπέμπει αὐτὸν Πιλάτῳ, καὶ ἐπιμείνας ἕως ἐνάτης ὥρας ἐν τῷ πραιτωρίῳ συγκεκλεισμένος. παράδοσις δέ τις ἔδραμε λεγόντων ἕως καὶ τῶν ἡμετέρων χρόνων,
