Luther sees in the Lord’s Supper the most concentrated form of the Gospel[5] because in it the death of Christ is proclaimed and the benefits of that saving death are bestowed in His body and blood given us to eat and drink.
This text is chosen for Maundy Thursday and involves eating and drinking with God—in His presence, real presence. This is only possible with the shedding of blood.
As preachers approach Holy Week, it is sometimes difficult to plan ahead. With a number of sermons to prepare, it can sometimes feel like you’re just trying to keep your head above water, say whatever the given text says for that service, and move on preparing the next.
