I repeat what I have already said: If any person preaches to you a "gospel" other than what you have already received [from us apostles], he should be cut off from God's [salvation].

They had only heard it said about me, "This person, who had once persecuted us [Christians], is now preaching the faith he once made havoc of."

But, when I saw that they did not act in harmony with [the principles of] the truth of the Gospel [message], I said to Cephas in front of everyone, "If you, being a Jew, act like a Gentile [by showing such discrimination], how do you expect to persuade Gentiles to live like Jews [i.e., like Christian Jews who are taught to love all people]?"
