Luke 22:7-23 The Lord’s Supper-The Christian Passover.
The Day of unleavened bread was the day when the Passover lamb was to be sacrificed (vv. 7-8). This is what Jesus came to fulfill. This also speaks to the conditions surrounding the practice of this celebration and who may or may not participate (Cf. Ex. 12). Paul reiterated this point. “For indeed Christ, our Passover, was sacrificed for us. Therefore let us keep the feast…with the unleavened bread of sincerity and truth” (I Cor. 5:7-8; 10:16; 11:23-26). This was the supper Jesus would share with His disciples (vv. 9-13 Cf. Mt. 26:17-19). Just as we now call the Sabbath ‘the Lord’s Day’, what we call ‘the Lord’s Supper’ is the Christian Passover. Not only were they partaking of the Passover at this time, but Jesus said that He would eat of it again when “it is fulfilled in the kingdom of God” (v. 16 Cf. Mk. 14:25). Jesus did not abolish the Passover, He fulfilled it and continues it in His kingdom (Cf. Rev. 19:9).
The unleavened Passover bread, that is, without sin, found fulfillment in the body of Christ offered once for all, which we also partake of in remembrance of Him (v. 19 Cf. Heb. 9:25-28; I Pet. 2:24). The cup which Jesus took was the cup of the Passover, this is what He gave thanks for and had distributed among the twelve (v. 17). Again, He would not drink of it again “until the kingdom of God comes” (v. 18). This was now the meal of the new covenant fulfilled. “This cup is the new covenant in My blood, which is shed for you” (v. 20). Yet not all those who partook of this outward administration of the covenant were children of promise (vv. 21-22 Cf. Mt. 26:23-24; Jn. 13:21). Judas had made his promise to another (v. 6 Cf. Mk. 14:17-18). Nevertheless, this was according to God’s sovereign will and purpose (Cf. Acts 2:23). Apparently Satan’s possession of him was not obvious to the rest (vv. 3, 23 Cf. Jn. 13:26-27).
