He has also made us competent as ministers of a New Agreement [i.e., between Himself and mankind].

1 Corinthians 10:16

Does not the "cup of blessing," which we bless, signify a fellowship with Christ's [physical] blood? [Note: This was the cup used at the close of the Passover meal and was called this because of the prayer of thanksgiving offered for it. Paul refers to such a prayer in connection with its use in the Lord's Supper]. Does not the bread that we break signify a fellowship with Christ's [physical] body?

1 Corinthians 11:27-28

Hebrews 9:15-20

Therefore, Christ is the Mediator of a New Agreement, so that [all] those people who have been called [by God] can receive the promise of the never ending inheritance. [This is possible because] a death has taken place for the redemption of [people's] sins who lived under the first Agreement.

Hebrews 13:20
