Objection
We believe in Jesus Christ, so we are Christians.
What is true
Latter-day Saints do affirm Jesus Christ as Savior and Redeemer.
Why it is not enough
The question is which Jesus and which doctrine of God. Christianity confesses the eternal Son, not a Savior placed inside a premortal spirit-family system.
Key question: Do you affirm Jesus as begotten, not made, consubstantial with the Father?
The name Jesus is not the whole claim
Christianity is not defined by whether a community uses the name Jesus with devotion. The New Testament itself warns that another Jesus and another gospel can be preached with religious seriousness.
The doctrinal question is whether Jesus is confessed as the eternal Son through whom all created things were made, or as the Firstborn spirit Son within a premortal family framework.
LDS devotion does not settle Christology
LDS sources honor Jesus as Savior, Redeemer, Jehovah, and chosen leader. Those statements should be acknowledged rather than dismissed.
The disagreement remains because the LDS framework includes Heavenly Parents, spirit children, a premortal council, and Lucifer as a rebellious spirit son. Christianity says the Son is uncreated God and Creator of every created being.
