Indeed, you must not delve deeply but maintain a very superficial view of Biblical language on eating if you texts maintain such must be literal. Which again, to be consistent in your literalism, means David poured out water made blood, and Jesus lived by eating the Father's flesh, and souls were dead until they consumed the corporeal body of Christ,
Not superficial at all.
The OT is not the NT and what happened in the OT is but a foretaste of what was to come in Jesus.
The Word did indeed exist from all eternity, but the flesh of Jesus did not exist until His conception.
Also, Jesus never says He eats of the Father’s flesh. That would be impossible as the Father has no flesh. What He said was that He had meat you know not of. Or in the KJV version, food to eat that you know not of.
Further, there is nothing in Catholic teaching that says that souls are dead until they consume the body of Christ. The soul is immortal, the life of which Christ speaks is life in the Kingdom of God.
Literalism is not an all or nothing concept concerning Scripture. Both extremes, rejecting all literalism or taking every passage literally has been used to divide Christ’s church.
