Encyclopedia of Mormonism, pg. 85; “To meet the demands of the Atonement, the sinless Christ went first into the Garden of Gethsemane, there to bear the spiritual agony of soul only he could bear. He “began to be sorrowful and very heavy,” saying to his three chief disciples, “My soul is exceeding sorrowful, unto death” (Mark 14:34). Leaving them to keep watch, he went further into the garden, where he would suffer “the pains of all men, yea, the pains of every living creature, both men, women, and children, who belong to the family of Adam” (2 Ne. 9:21). There he “struggled and groaned under a burden such as no other being who has lived on earth might even conceive as possible” (JC, p. 613).”
Hebrews 13:12; “Wherefore Jesus also, that he might sanctify the people with his own blood, suffered without the gate.”
The Mormon passage above is a prime example of heresy and what happens when you add to the word of God. Jesus did not pay for our sins in the Garden of Gethsemane. He sanctified the people with His blood outside the gates as it said in Hebrews – also see John 18:11.
