I have said it before and I now repeat it: whoever preaches a gospel to you that contradicts the gospel you have already received, God's curse be on him!

But I saw they were swerving from the true line of the gospel; so I said to Cephas in presence of them all, "If you live like the Gentiles and not like the Jews, though you are a Jew yourself, why do you oblige the Gentiles to become Jews?" ??15 We may be Jews by birth and not 'Gentile sinners,'

Now the Promises were made to Abraham and to his offspring; it is not said, 'and to your offsprings' in the plural, but in the singular and to your offspring ??which is Christ.
