Beware of unbelieving dogs. Watch out for workers of evil. Be on guard
against those who mutilate. It is we who are the circumcision, who worship
in the spirit of God and glory in Christ Jesus rather than putting our
trust in the flesh though I can be confident even there.  If anyone
thinks he has a right to put his trust in external evidence, all the more can I!

Footnote:

3, 2-4, 1:  The Judaizers are called unbelieving dogs (the customary
Jewish term at the time for Gentiles, here applied ironically) and workers
of evil.  Their urging of the religious rite of circumcision upon
Christians is regarded as mutilation (v 2).  The apostle declares that
Christians, who possess the true worship prefigured by circumcision, have
no need of this religious rite (v 3).  He offers himself an example of one
reared in the Jewish tradition of circumcision and the law, which he
thought it his duty to defend by persecuting the Christian communities
(4ff).
