キリスト教綱要
Communion under both kinds for the whole congregation was a central issue for the Protestant reformers, since they believed that it had been specifically commanded by Jesus at the Last Supper. John Calvin in his seminal 1536 work, "Institutes of the Christian Religion", wrote; 'For Christ not only gave the cup, but appointed that the apostles should do so in future. For his words contain the command, "Drink ye all of it." And Paul relates, that it was so done, and recommends it as a fixed institution (First Epistle to the Corinthians )'.
