Have you ever done a study on the furniture of the Tabernacle? Such as on gold? Gold symbolizes deity. And in 1Cor 3:12-13 it says if any man build upon this foundation, gold, silver, precious stones, wood, hay, stumble; Every mans work shall be manifest...
In other words, if you worship Jesus as God, then you will be rewarded. Silver represents redemption as precious stones represent people you win to Christ.
If it wasn't important to God that you recognize Jesus is God, then you wouldn't be rewarded at the judgment seat of Christ.
As far as the churches go, many condemn those who do not believe in the Godhead. However, salvation is a gift, and God doesn't take a gift back just because a person is without understanding on a Bible Doctrine.
But its also worthy to note that if a man does not confess Jesus Lord and believe He was raised from the dead, then he is not saved. Romans 10:9-10.
And another point I would like to make is, 1Timothy 3:16, Paul made it clear that the Godhead (Trinity) was a mystery.
Jesus made it clear, that the mysteries of the kingdom of God was given to the disciples, but to others in parables so that seeing they may not see, hearing they may not hear. Luke 8:10. And the Trinity is one of those messages of the kingdom of God, for Paul preached the gospel of the kingdom of God, Acts 20:24-25.
And another thing I will mention is God spoke about the Trinity in the Old Testament, Isaiah 48:16. Hope this helps you.
May the grace of God be with you.
