1:6 another gospel. The word “another” in this verse is heteros, meaning “another of a different kind.” That is, any gospel that is not centered on “the grace of Christ” is not just an alternative gospel; it is a false gospel—no gospel at all.

1:7 not another. In verse 7, on the other hand, the word for “another” is allos, which means “another of the same kind.” Galatians 1:6–7 stresses that the so-called gospel that was misleading the Galatians was not really one with just minor variations from the true gospel, but was altogether opposite to it, a false gospel.

1:8 angel from heaven. Note Revelation 14:6,7, which tells how, during the coming tribulation period, God will send an angel to preach the “everlasting gospel” from the heavens. The message of the angel will exhort people to worship the true God who had created all things. This obviously can only be the same gospel that Paul said that “we have preached unto you.” The gospel thus includes the creation as the foundation of all things, as well as the death and resurrection of Christ (I Corinthians 15:1-4) for our sins. It also includes the coming eternal kingdom when He will reign over all things (Matthew 4:23). We must accept it by grace through faith (Ephesians 2:8-9).

1:8 accursed. “Accursed” is the Greek anathema, referring to being dedicated to a false god, and therefore under the curse of God.
