2 Timothy 1:3

Origen de Principiis Book II

, that "on these two commandments hang the law and the prophets? "For how shall that which is strange and foreign to God depend upon Him? And when Paul says, "I thank my God, whom I serve my spirit from my forefathers with pure conscience,"[43]

Origen Against Celsus Book V

Let it be admitted, then, that there are amongst us some who deny that our God is the same as that of the Jews: nevertheless, on that account those are not to be blamed who prove from the same Scriptures that one and the same Deity is the God of the Jews and of the Gentiles alike, as Paul, too, distinctly says, who was a convert from Judaism to Christianity, "I thank my God, whom I serve from my forefathers with a pure conscience."[192]
