They have a gospel that believes that God chose who would be saved before the foundation of the world and who would be damned. That's "Another gospel."
Its not a "gospel" to believe that, that is what the bible says. Its doctrine.
Ephesians 4:1 For
He chose us in Him before the foundation of the world to be holy and blameless in His presence. In love 5
He predestined us for adoption as His sons through Jesus Christ, according to the good pleasure of His will,…
What is His will? That men turn from sin and turn to Him.
1 Timothy 2:4 This is good and pleasing in the sight of God our Savior, 4who desires all men to be saved and to come to the knowledge of the truth.
