Dialogue with Trypho 30Christians possess the true righteousness.

"But impute it to your own wickedness, that God even can be accused by those who have no understanding, of not having always instructed all in the same righteous statutes. For such institutions seemed to be unreasonable and unworthy of God to many men, who had not received grace to know that your nation were called to conversion and repentance of spirit, while they were in a sinful condition and labouring under spiritual disease; and that the prophecy which was announced subsequent to the death of Moses is everlasting. And this is mentioned in the Psalm, my friends. And that we, who have been made wise by them, confess that the statutes of the Lord are sweeter than honey and the honey-comb, is manifest from the fact that, though threatened with death, we do not deny His name. Moreover, it is also manifest to all, that we who believe in Him pray to be kept by Him from strange, i.e., from wicked and deceitful, spirits; as the word of prophecy, personating one of those who believe in Him, figuratively declares. For we do continually beseech God by Jesus Christ to preserve us from the demons which are hostile to the worship of God, and whom we of old time served, in order that, after our conversion by Him to God, we may be blameless. For we call Him Helper and Redeemer, the power of whose name even the demons do fear; and at this day, when they are exorcised in the name of Jesus Christ, crucified under Pontius Pilate, governor of Judaea, they are overcome. And thus it is manifest to all, that His Father has given Him so great power, by virtue of which demons are subdued to His name, and to the dispensation of His suffering.
