“Then Iesus sayd vnto them, Uerely, verely I say vnto you, Except yee eate the flesh of the sonne of man, and drinke his blood, yee haue no life in you.”
1611 King James Version (KJV)
6:53 Unless ye eat the flesh of the Son of man - Spiritually: unless ye draw continual virtue from him by faith. Eating his flesh is only another expression for believing.
Joh 6:53 Except ye eat of the flesh of the Son of man, and drink his blood. Appropriate these by faith. Whosoever by faith trusts in the death of Christ and is "baptized into his death" (Ro 6:3), spiritually partakes of the body and blood of Christ. So does he also who eats in loving remembrance of him the emblems that represent his body and blood. Joh 6:63 shows that his words must be taken in a spiritual rather than a literal sense.
