What Does Matthew 26:28 Mean?

For this is my blood of the new testament, which is shed for many for the remission of sins. This verse contains concentrated gospel theology. 'My blood' (τὸ αἷμά μου/to haima mou) refers to Christ's lifeblood, soon to be poured out on the cross. Blood represents life (Leviticus 17:11); Jesus would give His very life as payment for sin.

'Of the new testament' (τῆς καινῆς διαθήκης/tēs kainēs diathēkēs)—better translated 'new covenant.' Jesus establishes a new covenant, fulfilling Jeremiah's prophecy (Jeremiah 31:31-34). The old covenant, based on Israel's obedience and animal sacrifices, proved unable to save (Hebrews 8:7-8). The new covenant, ratified by Christ's blood, accomplishes what the old could not: complete forgiveness and transformed hearts.

'Which is shed' (ἐκχυννόμενον/ekchynnomenon)—present passive participle: 'being poured out.' Though crucifixion was hours away, Jesus spoke prophetically as if it were already happening. His death was certain, decreed in God's eternal plan.

'For many' (περὶ πολλῶν/peri pollōn)—not 'all' indiscriminately but 'many,' the elect chosen before time for salvation. Christ's blood is sufficient for all but efficient for the elect. He died as substitute for His people (Isaiah 53:11-12), actually bearing their specific sins and securing their certain redemption.

'For the remission of sins' (εἰς ἄφεσιν ἁμαρτιῶν/eis aphesin hamartiōn)—the purpose of the shedding: forgiveness, pardon, release from sin's guilt and penalty. Atonement is not potential but actual; Christ's blood doesn't merely make forgiveness possible but accomplishes it for those for whom He died.
