This last Easter service was extremely difficult for me as I found out in our WELS church that communicants could choose between wine or grape juice.
From Luther's Catechism:
397. What are the earthly elements in this sacrament?
The earthly elements are bread and wine.
My understanding from my three years of Catechism at a WELS church, has always been that it was wine that was used at the Lord's Supper.
When did Scripture change and now grape juice is an acceptable choice?
Shouldn't we stick to what the Bible states? The cup contained wine. Even Luther states this in defining the sacrament of the Altar. As stated in Luther's Catechism, "under the bread and wine."
