3 But it is greatly to be wondered at, how it has come to pass that, while affirming that they have found out the mysteries of God, they have not examined the Gospels to ascertain how often after His baptism the Lord went up, at the time of the passover, to Jerusalem, in accordance with what was the practice of the Jews from every land, and every year, that they should assemble at this period in Jerusalem, and there celebrate the feast of the passover. First of all, after He had made the water wine at Cana of Galilee, He went up to the festival day of the passover, on which occasion it is written, “For many believed in Him, when they saw the signs which He did,” as John the disciple of the Lord records.
Then, again, withdrawing Himself [from Judæa], He is found in Samaria; on which occasion, too, He conversed with the Samaritan woman, and while at a distance, cured the son of the centurion by a word, saying, “Go your way, your son lives.” Afterwards He went up, the second time, to observe the festival day of the passover in Jerusalem; on which occasion He cured the paralytic man, who had lain beside the pool thirty-eight years, bidding him rise, take up his couch, and depart.
Again, withdrawing from thence to the other side of the sea of Tiberias, He there seeing a great crowd had followed Him, fed all that multitude with five loaves of bread, and twelve baskets of fragments remained over and above. Then, when He had raised Lazarus from the dead, and plots were formed against Him by the Pharisees, He withdrew to a city called Ephraim; and from that place, as it is written “He came to Bethany six days before the passover,” and going up from Bethany to Jerusalem, He there ate the passover, and suffered on the day following.
Now, that these three occasions of the passover are not included within one year, every person whatever must acknowledge. And that the special month in which the passover was celebrated, and in which also the Lord suffered, was not the twelfth, but the first, those men who boast that they know all things, if they know not this, may learn it from Moses. Their explanation, therefore, both of the year and of the twelfth month has been proved false, and they ought to reject either their explanation or the Gospel; otherwise [this unanswerable question forces itself upon them], How is it possible that the Lord preached for one year only?
