Throughout much of the Church’s history Word and sacrament have not gone together. During the Middle Ages Mass would occur with Lord’s Supper being offered in part (bread not wine) but without preaching.
You’ve no doubt been to many worship services, in fact most Protestant worship services, where the Word is taught, but the sacrament, the Lord’s Supper, isn’t offered.
Many Reformers in the sixteenth century wanted Word and sacrament to go together the way they do in Scripture. Martin Bucer tried to get the whole Christian community into the cathedral in Strasbourg to hear the Word and receive communion every week, and so did Calvin in Geneva, but it didn’t happen.
They wanted this because the Supper is the sign and seal of God’s Word, assurance that it’s really offered to us. It is put in our hands and in our mouths showing His fatherly care and hospitality to us. We eat and drink acknowledging that we accept His grace. If nothing is said, if there’s no Word, then what are we receiving? And if we hear the Word, it says “Taste and see that the Lord is good.” Jesus said “Do this in remembrance of me.”
