Swingli and Luther's Disagreement on the Eucharist

Swingli and luther disagreed over the sacrament of the eucharist. Swingle thought anabaptists were giving too much power to outer works, he says. Being baptized cannot cleanse us from in but is only a sign that a person is pledged to the christian faith,. This, he insisted, is the meaning of the word sacrament - a sign or symbol and nothing more.
