Philippians 3:18

Who these enemies were becomes clear in the next verse. Here we learn that there were many of them, though they were probably not in the Philippian church or Paul would probably have addressed them differently. These individuals caused the apostle much grief because they misled Christians. Perhaps he described them as enemies of the cross because what they taught was contrary to the spirit of obedience to God that had led Jesus to the cross (cf. Philippians 3:10).
