From a forum thread:
{{___ What would be the simplest statement regarding what would constitute "another gospel" in your opinion?
{{___ Galatians 1:6-8 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not anotheBut though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.r; but there be some that trouble you, and would pervert the gospel of Christ. }}
The other gospel that Paul was writing against was one that required something in addition to the grace (unmerited favor) of Christ as the grounds or basis of salvation.
In the case of the Galatians the something else was circumcision.
But anything that man can boast about may change the Gospel (of grace) into another gospel.
As William Kelly said, the error of the Galatians is ubiquitous.
We are all, I believe, crypto-Galatians. It is all too human to find something that we can boast about in order to explain our blessings.
Ephesians 2:8-9 KJV For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: (9) Not of works, lest any man should boast.
