When Christ said take and drink from this chalice, this IS MY BLOOD.....what do you suppose that He meant?????
Paul tells us.
23For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread; 24and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” 25In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.”
26For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes. 1 Corinthians 11:23-26 NASB
He was using a metaphor.
Jesus did not come to change or break the Law but to fulfill it.
Therefore He could not have changed the wine to literal blood.
Metaphor definition.
https://literarydevices.net/metaphor/
Metaphor is a figure of speech that makes an implicit, implied, or hidden comparison between two things that are unrelated, but which share some common characteristics. In other words, a resemblance of two contradictory or different objects is made based on a single or some common characteristics.
In simple English, when you portray a person, place, thing, or an action as being something else, even though it is not actually that “something else,” you are speaking metaphorically. For example, the phrase, “My brother is the black sheep of the family,” is a metaphor because he is not a sheep, nor is he black. However, we can use this comparison to describe an association of a black sheep with that person. A black sheep is an unusual animal, which typically stays away from the herd, and the person being described shares similar characteristics.
Furthermore, a metaphor develops a comparison that is different from a simile, in that we do not use “like” or “as” to develop a comparison in a metaphor. It actually makes an implicit or hidden comparison and not an explicit one.
Common Speech Examples of Metaphors
Most of us think of a metaphor as a device used in songs or poems only, and that it has nothing to do with our everyday life. In fact, all of us in our routine life speak, write, and think in metaphors. We cannot avoid them. Metaphors are sometimes constructed through our common language, and they are called “conventional metaphors.”
For instance, calling a person a “night owl,” or an “early bird,” or saying “life is a journey,” are common examples of metaphors heard and understood by most of us. Below are some more conventional metaphors we often hear in our daily lives:
-My brother was boiling mad. (This implies he was too angry.)
- The assignment was a breeze. (This implies that the assignment was not difficult.)
- It is going to be clear skies from now on. (This implies that clear skies are not a threat and life is going to be without hardships)
-The skies of his future began to darken. (Darkness is a threat; therefore, this implies that the coming times are going to be hard for him.)
-Her voice is music to his ears. (This implies that her voice makes him feel happy)
- He saw the soul of dust when passing through the dust storm.
- Chaos is the breeding ground of order.
- War is the mother of all battles.
- Her dance is a great poem.
- A new road to freedom passes through this valley of death.
- My conscience is my barometer.
- His white face shows his concern.
- His kisses are like roses.
- He married her to have a trophy wife.
- Laughter is the best medicine.
- Words are daggers when spoken in anger.
- His words are pearls of wisdom.
Um, we have His words that tell us ... But you cannot hear them as Jesus went on to say He would not drink of the vine (referring to the wine in the cup) again until drinking it with them (the disciples) in the kingdom. You really ought to read the whole passage. You will learn, perhaps.
Oh; about the same thing HE meant when HE said who ever drank it would NEVER thirst again.
