I see you have taken me off of ignore, @Jane_Doe22.Just to be obstinate---
There is technically a third option: both could be right and they are using different words to talk past each other, or talking about different aspects of the same answer.
In Protestantism with a "sola scriptura" foundation, it really does come down to that individual's interpretation of scripture and none can really be proven right over the other. It's very silly to watch Protestants try to do just that. Rather, the real foundation of Protestantism (and Christianity as a whole) is the individual's relationship with God.
It has been one of my contentions with you that Mormonism defines the words that we find in the Bible differently than we might find in normal defining of terms...so technically you may be right...if a Mormon used words defined by Mormonism, and used them to say what is truly Christian doctrine; but someone who truly believes Christian doctrine disagreed because the definitions were different...but if that same Christian knew the Mormon definitions of the terms he might have agreed, then any Mormon listening might find the gospel preached to them in Mormon terminoligy because the meaning of what was said would be in accordance with the real gospel...maybe something you can do, @Jane_Doe22, can do, once you have converted to real Christianity.
