15:1 certain men. Possibly these men were some of the priests who had become obedient to the faith, or at least they were of the Pharisees’ sect (Acts 15:5). At any rate, although these men believed in Jesus as the Messiah and in His substitutionary death and resurrection, they still felt that a convert must be either a Jew or Jewish proselyte to be eligible for salvation in Christ. They were called “Judaizers” and came to be a real problem in the early church. This particular form of legalism is not much of an issue today, but the problem of those who would add works to faith in Christ as a requirement for salvation is still very common. While genuine faith will surely produce obedience and good works (note Ephesians 2:8-10), they follow saving faith as a result, not as a condition.
