Using grape juice is a practice that began right here in Vineland when Dr. Thomas Welch, a dentist was visited one Sunday afternoon by a drunken man, who had begun his binge with communion. Welch was a prohibitionist and the Communion Steward at Vineland Methodist Church, so he experimented with pasteurizing grape juice specifically to produce a wine for communion that would not lead a person into drunkenness. He called it "Dr. Welch’s Unfermented Wine." His process worked and his son Charles marketed the product and the process. Thus Welch’s Grape Juice is now a landmark in our grocery stores.
I do not oppose the use of fermented wine in communion, but I use grape juice for the same reason it was invented. Some people struggle with alcoholism and I would rather they did not struggle because of their worship.
