Common misinterpretations of Luke 22:20 include viewing the cup as literally transforming into Jesus' blood, as in some transubstantiation teachings that ignore the metaphorical Passover language and symbolic cup tradition; others reduce it to a mere historical ritual devoid of ongoing spiritual power, overlooking its role in commemorating atonement; some erroneously limit its application to church elites or specific denominations, neglecting the inclusive 'for you' that points to universal availability through faith rather than institutional mediation.
Luke 22:20
King James Version (1769)
20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
In Luke 22:20, Jesus institutes the Lord's Supper during the Passover meal, declaring the cup to symbolize the new covenant ratified by his own blood shed for humanity's redemption, fulfilling Old Testament prophecies like Jeremiah 31:31-34 and emphasizing his sacrificial death as the basis for forgiveness, reconciliation with God, and the inauguration of a new spiritual relationship available to all who partake in faith.
