I used to like the old “spiritual springboard” concept to the development of LDS doctrine. Made sense to me in my youth. Now I see it as the roots of the corrupt doctrine.

I picture someone on land but on a diving board. They spring off into the air and ocean. They no longer have contact with the land but are flailing in the air than going deep down. The land no longer matters.

I accept no one who claims to have once been connected with the Bible and Book of Mormon, lost that connection, eschews that connection and is dog paddling around with new ideas either not found “on land” or directly contradicts them.

This is not any kind of springboard. This is rejection and forsaking the truth and going off into uninspired innovation and fanciful self-delusion.

Jeremiah knew this.

Jeremiah 2:13 For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water.

Fallen man always prefers gospel alternatives so, if this “spiritual springboarder” teaches his doctrine, he will have much success.

Korihor stated, I have taught his [the devil] words; and I taught them because they were pleasing unto the carnal mind; and I taught them, even until I had much success, insomuch that I verily believed that they were true; and for this cause I withstood the truth, even until I have brought this great curse upon me.

Sorry. There is no springboard. There is a rock. One can build on it or springboard off of it. Jesus said,

Verily, verily, I say unto you, that this is my doctrine, and whoso buildeth upon this buildeth upon my rock, and the gates of hell shall not prevail against them.
And whoso shall declare more or less than this [springboarding], and establish it for my doctrine, the same cometh of evil, and is not built upon my rock; but he buildeth upon a sandy foundation, and the gates of hell stand open to receive such when the floods come and the winds beat upon them.
