Read the series.
Having come to a conclusion about the foremost question in the debate about the range of the New Covenant and its connection to Jesus Christ, I want to spread out before the reader my reasons for identifying Him with the NC. These reasons are roughly, exegetical, theological, and devotional. I see no need to go back over the arguments for Luke 22, 1 Corinthians 11, 2 Corinthians 3, and the the Book of Hebrews (although I shall look into Heb. 9:16-17). However, I will provide a summary of the teaching of these passages as I interpret them, and add several further thoughts.
Some Exegetical Arguments
In Luke 22:19-20 our Lord first refers to His body:
This is My body which is given for you; do this in remembrance of Me. (Lk. 22:19)
The body of Christ was broken for the disciples, but who believes that it was broken for them only? As Paul says, it was broken also for all Christians. It is not called “the body of the New Covenant,” so there is no division of His body between supposed NC saints and non-NC saints. Then we come to the cup:
Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you.” (Lk. 22:20)
