I studied about the sacrament in my Come, Follow Me studies this week. The Savior Jesus Christ presented a sermon known as the Sermon on the Mount, while he lived on earth. He presented a similar sermon after His Resurrection to people who lived in ancient America. This sermon is known as the Sermon at the Temple.
After the Savor taught the Beatitudes and that we are to hold up His light to the world, He commanded His disciples to bring forth some bread and wine. While they were gone to get the bread and wine, He commanded the multitude to sit down upon the earth.
And when the disciples had come with bread and wine, he took of the bread and brake and blessed it; and he gave unto the disciples and commanded that they should eat.
