What is syncretism? Syncretism is the attempt or tendency to combine or reconcile differing beliefs, as in philosophy or religion. To syncretize is to combine differing beliefs.*

Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son. If there come any unto you, and bring not this doctrine, receive him not into your house, neither bid him God speed: For he that biddeth him God speed is partaker of his evil deeds. II John 1:9-11

As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed. Galatians 1:9
