Mankind are all subject to sin. Over a lifetime we are all corroded by this environment. To preserve this creation, death has been introduced so that no matter how far men may fall from God's grace, their lives will end. In their place, children who are innocent before God come into this world. It is by and through children that hope returns, innocence is renewed and creation continues. Little children are where God's great renewal of mankind takes place. If not for them, this world would have ripened in iniquity long ago.
The angel draws a parallel between Adam's fall and Christ's atonement. (Mosiah 3: 16.) The one brought death to all, the other brings life to all. Even those who will squander their opportunity for more are still redeemed from death through Christ.
Then the angel declares where salvation (something more than rising from the grave) is obtained. It is completely in Christ. "[T]here shall be no other name given nor any other way nor means whereby salvation can come unto the children of men, only in and through the name of Christ, the Lord Omnipotent." (Mosiah 3: 17.) It is not a church. It is not an ordinance. It is not an organization, initiation, family, relationship with, or promise from a man or men, nor any other means. It will be Christ, or it will not happen.
What, then, does it mean to be saved "in and through the name of Christ?"
What is His name? Or, more correctly, what are His names? How does one become saved through His name?
King Benjamin will later have his people take upon them the actual name of Christ. (Mosiah 5: 6-7.) How are you "called by the name of Christ?" Do you, literally need to become "Christ?" That is, do you literally need to become a "Messiah" or a "Christ" or an "anointed one?" Because the name "Christ" is akin to the word "christened" or "christening," meaning you have become anointed.
How do you become anointed? Is it through application of physical oil to the physical skin? Is that an anointing in the sense that Christ was anointed? Or, is the physical anointing a symbol of another kind of anointing, another kind of christening? If so, what does that entail?
When the angel marks a man "in the forehead" (Rev. 7: 3; D&C 77: 9) is that literal? What kind of anointing, or christening, or seal is involved?
Did Christ set the pattern? Does it mean to "take upon you His name" that you, in like manner, are christened, anointed or sealed? Can you be His without this? Can you take His name upon you without conforming to the same pattern as Christ, who is the "prototype of the saved man." (Lectures on Faith, 7: 15-16.)
