Please keep in mind that besides the Christian’s deified rabbi not being a Christian nor were there any churches in existence when he died his mission to get Jews observing Torah in letter and in Spirit was just that - a mission to Jews only.
He never even had a mission to get the non-Jews to follow the Ten Commandments which the B’nai Noach are supposed to do.
You will need to explain that to the Samaritan Woman at the well.

He didn't come that all would follow the Ten Commandments. He came to reconcile man with God. In doing so, it makes sense that these reconciled men would follow God's Law out of love for their Author.
