"And God spake all these words, saying," - Exodus 20:1 KJV
"And Moses gathered all the congregation of the children of Israel together, and said unto them, These [are] the words which the LORD hath commanded, that [ye] should do them." - Exodus 35:1 KJV
Jesus said to the apostles who superintended the writing of the New Testament…
"But the Comforter, [which is] the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you." - John 14:26 KJV
The gospels contains the teaching of Jesus Christ who is God in the second person of the trinity but Luke sets the tone for the rest of the New Testament when he says…
"The former treatise have I made, O Theophilus, of all that Jesus began both to do and teach, Until the day in which he was taken up, after that he through the Holy Ghost had given commandments unto the apostles whom he had chosen:" - Acts 1:1-2 KJV
This makes it clear that the rest of the New Testament is still the teaching of Jesus.
So you're going to dictate your interpretation of the Bible based on your understanding of other disciplines and imposing that on American citizens through policy, in violation of the first amendment? There's no dispute that, that is what you're doing. The dispute is whether or not it's legal under the Bill of Rights.
