25 These memorials I have written for our brethren and beloved, the children of the Church of God, that when these come into their hands in various places, and when they read in them, they may also remember my insignificance in their prayers, and may know that I am a sinner also, and fall short; but that this is my faith, that I have set forth from the beginning and written, in these chapters written (by me). Faith is the foundation, and upon faith (rest) the works that become it.
And after Faith (I wrote) that there are two commandments of Love. And after Love, I have written of Fasting, in its demonstration also along with its works. And after Fasting, I wrote of Prayer in its fruit and in its works. And after Prayer, have written about War and about whatever Daniel wrote concerning the kingdoms. And after War, I have written of the exhortation for Monks. And after the Monks, I have written about Repentance.
And after Repentance, I have written about the Resurrection of the dead. And after the Resurrection of the dead, I have written about Humility. And after Humility, I have written of the Pastors, the teachers. And after the Pastors, I have written about the Circumcision in which the people of the Jews pride themselves. And after the Circumcision, I have written about the Passover, and about the fourteenth day. And after the Passover, I have written about the Sabbath, in which the Jews are puffed up.
And after the Sabbath, I have written an Exhortation, on account of the dissension which happened in our days. And after the Exhortation, I have written about Meats, those that the Jews deem unclean. And after the Meats, I have written about the Gentiles, that they have entered in and become heirs instead of the original people. And after the Gentiles, I have written and proved that God has a Son. And after the Son of God, I have written against the Jews, who speak injuriously about Virginity.
And after the apology about Virginity, I have written again Against the Jews, who say:— “It is appointed for us to be gathered together.” And after that defence, I have written about Almsgiving to the Poor. And after the Poor, I have written a demonstration about The Persecuted. And after the Persecuted, I have written at the end about Death and the Last Times. These twenty-two discourses have I written according to the twenty-two letters of the alphabet.
The first ten I wrote in the six hundred and forty-eighth year of the kingdom of Alexander the son of Philip the Macedonian, as is written in the end of them. And these twelve last I wrote in the six hundred and fifty-fifth year of the kingdom of the Greeks and of the Romans, which is the kingdom of Alexander, and in the thirty-fifth year of the Persian King.
