Yup. Mormons believe all humans (including Jesus Christ) are the sons and daughters of God. Even Satan was a son of god. Since we all have the same father, we are all brothers and sisters. You appear to be saying that anyone who believes we do not all share the same spiritual father cannot be a Christian. On what do you base your belief?
And what does this have to do with justice, mercy, grace, salvation, and Christ's atonement, which is the basis of Christianity.
