By Reformed Theology, Which Beliefs Accompany Saving Faith?

Which articles do Reformed Theologians say are always part of our salvation? (For instance, I have heard recognized figures teach that saving faith will always carry with it a recognition of the Deity of Jesus Christ. And I’ve heard them say it is not necessary to believe in election.) ______ **EDIT**: Including [an answer](https://christianity.stackexchange.com/a/86008/54533) , we believe it will be limited to things that affect Romans 10:9, etc. King James Version >9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. This would mean faith and trust in a false Christ would make a reformed person think someone is not saved (hence Christ’s Deity is an example). Are things not embracing the true Christ the only heresy impacting Romans 10:9 and salvation? Also I wonder which aspects of Christ they would say must be accepted.
