Jesus wants us to remember that he suffered anguish beyond our comprehension in the Garden of Gethsemane and on the cross when he sacrificed himself in order to—in a way we do not fully understand—pay for the wicked abominations and sins of the world, allowing forgiveness to become available to those who repent. To help us remember this, Jesus has commanded us to frequently perform the ritual of the sacrament.
You should attend church every week on the Sabbath to partake of the sacrament. Males should wear a suit—or a shirt and tie—with nice pants; females should wear a dress or a skirt. Bread and water will be distributed to be consumed by the congregation. Many Christian denominations believe the tokens of the sacrament literally become the flesh and blood of Jesus, but this is not so. It is only in a spiritual sense that we eat Jesus's flesh and drink his blood.
Jesus has emphasized that, for one’s own good, no one should be allowed to partake in the sacrament ritual who has sinned and remains unrepentant, for to do so can result in spiritual sickness and condemnation. "Ye shall not suffer any one knowingly to partake of my flesh and blood unworthily, when ye shall minister it," said the savior. "For whoso eateth and drinketh my flesh and blood unworthily eateth and drinketh damnation to his soul."
When you participate in the sacrament, you renew the sincere promise you made to Heavenly Father at baptism to follow his commandments for the rest of your life. You also promise to always remember the wounded body of Jesus Christ on the cross and that he shed his blood for the atonement of the world. Finally, you promise never to do anything that would bring shame upon the name of Jesus. In keeping these promises, you are granted the continuous guidance of the Holy Ghost.
