Lutherans from the very beginning sought to use their practice to teach what they believed in accordance with AC XXIV. This becomes all the more clear as you read through the Lutheran church orders of the Sixteenth and Seventeenth Centuries. In his book, Faith and Act: The Survival of Medieval Ceremonies in the Lutheran Reformation, Ernst Walter Zeeden has compiled all the pertinent information of what the liturgical practice (rites and ceremonies) of the nascent Lutheran church looked like. Here’s what Zeeden finds out about the ceremonies surrounding the administration of the Lord’s Supper.
You see the seriousness with which they treated the Sacrament during the consecration, administration, and thereafter. They believed that it is the true Body and Blood of our Lord Jesus Christ, just as He promised, and conformed their practice to bring that reality before the eyes of those who came to receive it.
Side note: If you’re going to reserve the Sacrament for your hospital and homebound, be sure to bring it to them in surplice in procession with the sacristan while he rings the bells.
