No. We have to believe ONE, singular, doctrine that The Lord Jesus Christ taught and the apostles expounded on. Acts 16:31
Believe/trust in the Person and work of the Lord Jesus Christ ALONE to be saved.
What we have today is people believing in His name and not His Person and work. They believe He lived and did great things. But they are trusting in their own FOLLOWING /imitating of Him to be saved.
Umm the whole Bible
is the Doctrine of Christ, the Word
is Jesus:John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.,John 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.Romans 10:17 So then faith cometh by hearing, and hearing by the word of God.
