In Luke 7 Jesus tells a woman that her faith has saved her to go in peace.
No mention of eating and drinking there.
Just her faith.
And right after John 6!
[26] And whilst they were at supper, Jesus took bread, and blessed, and broke: and gave to his disciples, and said: Take ye, and eat. This is my body. [27] And taking the chalice, he gave thanks, and gave to them, saying: Drink ye all of this. [28] For this is my blood of the new testament, which shall be shed for many unto remission of sins. Matthew; Chapter 26
