What did the Judaizers say was required in addition to faith for salvation?
The Judaizers taught that faith in Paul’s Gospel was insufficient; circumcision and observance of the Law of Moses were also required. They insisted that without these additions no one could be saved, thereby corrupting the truth that salvation is by faith plus nothing.
Les explains that the Judaizers came into the churches saying believers could not be saved merely by faith, but had to also practice circumcision and keep the Law of Moses, or they could not be saved. This, he says, polluted and corrupted Paul’s Gospel, like mixing water with wine. Paul’s Gospel declares that salvation is by faith plus nothing, so Paul wrote the letter to the Galatians to correct their error of believing something corrupt and perverted.
