Mainstream Mormons are used to communicating in a certain rhetoric, and anybody who strays from the accepted script is in trouble. If anybody doesn’t believe me, then just try restating standard orthodox Mormon doctrine, but do so in your own words. They won’t understand you.
If we once lived in the Presence of God, but do not do so now, then we need a Redeemer in order for us to return to the place and condition from whence we came. But, that Redeemer is us. Christ showed us how to do it, but it is we who must do it. That’s what it means to follow Christ and to believe in Christ. To follow Christ is to do what Christ did and live as he lived. To believe in Christ is to have faith that following Christ will redeem us.
