" Finally, the Reformers also agreed that worship should be in the vernacular and that the twofold structure of Word and sacrament be maintained. Zwingli was the only Reformer who disagreed with the desire to return to the ancient structure of Word and sacrament. His emphasis was on the Word only. Zwingli’s position remained the most influential in the circles of Calvinism, and, to the distress of John Calvin, quarterly communion, rather than weekly communion, became standard in the churches most influenced by Calvinism. This influence extended through the English Puritans to the Baptists, Presbyterians, Congregationalists, and independents and spread through them to most of American Protestant Christianity. "
