In Galatians, the Judaizers were willing to accept only part of the message and in the end got full condemnation. They believed in justification by faith, only not by faith alone. In Islam, Muslims accept Jesus as Messiah, only not as the Messiah who is Creator of the universe and Savior of the world.
Insiders and C5 proponents believe that the way to bridge the gap is by blending in to the community and in doing so softening the vast differences between Christianity and Islam. Paul’s perspective from Galatians can help us here.
First, Paul’s gospel was not palatable to the unconverted. His goal was not to tickle the ears but teach the evangel. “For am I now seeking the approval of man, or of God? Or am I trying to please man? If I were still trying to please man, I would not be a servant of Christ” (Gal. 1:10).
Apparently some were accusing Paul of being a flatterer, acting like a flag that flies in the direction of public opinion. Anathematizing to hell anyone who twists the gospel (Gal. 1:8-9) quickly put an end to this farce. Paul did not remove the rough edges or offense from the gospel. “But if I, brothers, still preach circumcision, why am I still being persecuted? In that case the offense of the cross has been removed” (Gal. 5:11).
Second, the only times Paul “contextualized” with his hearers is when he made life more difficult for himself, not easier. Hence, the “all things to all men” passages in 1 Corinthians 9. Any definition of contextualization that made it easier to be a follower or proclaimer of Jesus was foreign to Paul. John MacArthur wrote:
[Paul] was not advocating a marketing plan. He was not making a plea for ‘contextualization.’ He was not suggesting that the message be made more acceptable….He was calling for self-denial and sacrifice for the sake of proclaiming the unadulterated truth to those who do not know Christ.
In conclusion, our recent analysis of the Insider and C5 Movements demonstrates they misappropriate contextualization to Muslims by softening the theological differences between Islam and Christianity and discouraging suffering for Christ.
