The introductory words of The Fourth Book are as follows:
Christ Speaks to us as His Disciples.
“Come to Me, all you that labor and are burdened, and I will give you rest.”
“The Bread that I give you is My Flesh, for the life of the world.”
“Take and eat; this is My Body, which will be delivered up for you; do this in memory of Me.”
“Whoever eats My Flesh and drinks My Blood abides in Me, and I in him.”
“The words that I have spoken to you are spirit and life.”
