Read what I said. The name isn't important, understanding who Christ is and what he did is. If a Muslim converts to Christianity, but out of habit still refers to Christ as Isa, then he will still be saved because he/she has faith that Christ bore the punishment of his/her sins. Now most people who refer to Christ as Isa are Muslims, so they aren't saved, but it isn't because they call him Isa, it's because they don't trust him for their salvation.
It's also quite a predicament that Mormons are in right now. You say that you believe in the same Christ as Biblical Christians, but yet Joseph Smith's testimony about his vision stats that he was told that all current religions were wrong, that
"they draw near to me with their lips, but their hearts are far from me, they teach for doctrines the commandments of men, having a form of godliness, but they deny the power thereof." (
The Testimony of the Prophet Joseph Smith). Gordon B. Hinckley, your "prophet", also said these things:
Your religion's own prophets have said that they do not believe in the same Christ, and your religion is founded upon the idea that all other Christs are wrong. So to say you believe in the same Christ would be tantamount to condemning yourself as an apostate. Joseph Smith testified that in his vision that God told him that all current religions were wrong, which is the reason he used to found Mormonism. So if you believe that he actually had this vision, how can you now say that you believe in the same Christ as Biblical Christians, even excluding the vast number of contradictions between the Bible and the D&C?
