John was explicitly told to eat the scroll also.
John 7:38 He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.
I don't suppose you believe that literally do you?
“It was as sweet as honey.”
Revelation 10
So I went up to the angel and told him to give me the small scroll. He said to me, Take and swallow it. It will turn your stomach sour, but in your mouth it will taste as sweet* as honey. 10I took the small scroll from the angels hand and swallowed it. In my mouth it was like sweet honey, but when I had eaten it, my stomach turned sour.d 11Then someone said to me, You must prophesy again about many peoples, nations, tongues, and kings.*
The small scroll was sweet because it predicted the final victory of Gods people; it was sour because it also announced their sufferings. Cf. Ez 3:13
Eat can also mean to affect something by gradual consumption. Absorb, such as retaining the information.
Rivers of Living Water.* 37 On the last and greatest day of the feast, Jesus stood up and exclaimed, Let anyone who thirsts come to me and drink.u 38Whoever believes in me, as scripture says:
Rivers of living water* will flow from within him.v
39He said this in reference to the Spirit that those who came to believe in him were to receive. There was, of course, no Spirit yet,* because Jesus had not yet been glorified.w
Why wouldn't you want the Real Presence of Christ and the Holy Spirit(Body and Blood) in the Eucharist flowing like rivers throughout your body (flow within him)?
