Do You Avoid Using Jesus's Teachings?

If you believe the doctrine of the “Trinity” that is to say unless one “faithfully and firmly” believes “the Son is God” they “cannot be saved,” then can you tell me this? While teaching the Anthanasian Creed’s “the Son is God” as true, do you avoid using Jesus’s teachings? I’m asking because “the Son is God” has nothing in common with Jesus, let alone the all-knowing God of the Bible. I know this to be true because the teachings of Jesus, as laid out for us in the Bible, are true. God bless. In His Care… Jim
