Words of Mormon 1:15
And it came to pass that after there had been false Christs, and their mouths had been shut, and they punished according to their crimes;
I'm asking my self, what is a false Christ? Is a false Christ someone who claims to be Jesus but instead struggles with a mental disorder? Is a false Christ someone who "sets them self up as a light"? Christ in his visit to Americas says to "hold up your light that it may shine unto the world" but the next line informs us that HE is the light we are supposed to hold up (3 Nephi 18:24). Not ourselves. So perhaps holding ourselves up is a false form of Christ, by holding up something, or redirecting the focus towards something that isn't the true light (2 Nephi 26:29). What does it look like to "set yourself up as a light"? It's called priestcraft in the scriptures and in the above reference in Nephi. I don't know all the answers but I think the above is worth some thought.
Is a false form of Christ someone who says they say something "in the name of Christ" when they actually don't? Is it a false Christ when the words are lip service or just empty words that aren't really spoken in the name of Christ although his name is used? I think that could be a false form.
Along with the idea of false Christs, Satan can appear as a being of light (2 Nephi 9:9). He was the original false "Christ" who sought to claim glory and honor to himself due to his role in his own version of The Plan of Salvation. False Christ's may mean a lot of things. Especially if we look at "Christ" as a title. Someone could claim to be Jesus. Or someone could just be setting themselves up as a light, wanting others to look at them, follow them, and give them praise, or a person could use his name in vain. I think all of that would qualify among still other things that would be considered false Christs. Priestcraft is something scriptures warn about when speaking of the latter days. Warnings are pointless though if we don't allow ourselves to be warned.
In this Nephite society false Christs were punished. Weird,.... in our day I don't know that we have something equivalent unless a person violates the laws of the land. Not sure though, interesting to think about.
Tonight I happened to be looking at the bug zapper on the outside of my in-laws house. Bugs are attracted to a light source. In this case it's a false purple glowing light, and is a trap. They see the "light" and are lured in, and they don't survive the consequences. A good lesson for all of us to make sure we seek, and hold up the true light which is Jesus Christ.
