Second, nobody will deny that we have the holy sacrament of the altar, just as Christ himself instituted it and the apostles and the whole of Christendom have since practiced it. Thus we eat and drink with the whole of ancient Christendom from one table, and we receive with them the same one ancient sacrament; we have done nothing new or different. Consequently, we are one church with them, or as St. Paul says in I Corinthians 11 [10:17], “one body” and “one loaf” since we eat of one loaf and drink of one cup. So the papists cannot call us heretics or a new church, unless they first call Christ, the apostles, and the whole of Christendom heretics, as in truth they do, for we are one church with the ancient church, in one sacrament. (Luther’s Works, v.41, p.195)

First, nobody can deny that we, as well as the papists, have received holy baptism and because of that are called Christians. Now baptism is not something new, invented by us in our own day, but it is the same ancient baptism instituted by Christ, in which the apostles and the early church and all Christians have been baptized. If then we have the same baptism as the original, ancient (and, as the creed says, “catholic,” that is, “universal”) Christian church, and are baptized in it, then we belong to the same ancient universal church; and they like us, and we like them, are baptized with one baptism; and therefore there is no difference between us as to baptism. But baptism is the first and most important sacrament, without which the others are all nothing, as they must admit. This is why the papists cannot truthfully call us a different or a new or a heretical church, since we are children of the ancient baptism, together with the apostles themselves and all of Christendom, Ephesians 4 [:5], “one baptism.” (Luther’s Works, v.41, p.194-195)
