Matthew 26:27

27. Took the cup and gave thanks From the Greek word ευχαριστεω , eucharisteo, to give thanks, the Lord’s Supper is called the eucharist. For since it is taken in thankful remembrance of our Lord’s great work of redemption, so it is truly a thank offering, that is a eucharist.

Drink ye all of it That is, drink all ye of it. And Mark adds that they all drank of it. As our Lord here represents the future minister, so the disciples represent the future laity; and as our Lord here directs them to partake the cup, so the Church of Rome, which withholds the cup from the laity, is palpably disobedient to the Saviour’s command. Surely, as it is the blood which redeems, the Church of God should not be denied the participation of his blood.
