The are the same Body.
Are they really??? How many times does Jesus have to die for the forgiveness of sins???
Is this the Gospel or isn't it???
"Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand. By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures." [I Corinthians 15:1-4]
Note that "died" is past tense --
Note also that phrase "if ye keep in memory". What did Jesus say??? "Do This In MEMORY of Me". The remembrance aspect of the Lord's Supper was an aide to helping the church "keep in memory" that "Christ died for our sins according to the scriptures" -- a past tense and one time event.
The[y] are the same Body.
The body of the one Christ, who died and now lives. And since that Christ lives, it is "substantially and sacramentally" the body of the living Christ.
Here "substantially" does not mean "more or less" or "sorta kinda", but rather if you were to point at Jesus, should he appear, or punch Him or pinch Him, and say, "What's that?" you should get the same answer as you'd get if you were to point at the bread and the wine, to wit: "Jesus Christ, body and blood, soul and divinity."
I THINK that's the way to say it.
