Chellebelle asked some time ago if you had to believe in the Trinity to be saved. I think you have to believe in the deity of Christ to be saved.

Romans 10:9says “That if you confess with your mouth ‘Jesus is Lord’ and believe in your heart that God raised him from the dead, you will be saved.”

1 John 4:13:15 says “Whoever confesses that Jesus is the Son of God, God abides in him and he in God.”

1 John 2:23 “No one who denies the Son has the father; whoever acknowledges the Son has the Father also.”
