Since no conjunction is used between any of these three clauses, they must refer to the same class of people. Dogs are unclean (Lev. 11:27), the evil workers are evil, and the concision are those deserving of contempt. (Concision meaning mutilation, is a contemptuous term for circumcision. See note Gal. 5:121.) The dogs here are the Judaizers. In nature the Judaizers are unclean dogs, in behavior they are evil workers, and in religion they are the concision, people of shame. In such a book concerning the experience and enjoyment of Christ, the apostle warned the Gentile believers to be wary of such unclean, evil, and contemptible people.
