Martin Chemnitz carried forward the theology of Martin Luther. And here, Chemnitz argues the case for the real presence of Christ at the Lord's Supper. His argument relies on the words of institution, which he takes literally against those who take it figuratively (i.e., John Calvin, Peter Martyr, etc.). In his view, the literal sense means that Christ's really and truly unites to the bread and wine at the Supper. And when we eat the Supper, we eat it sacramentally. He refuses to give an exact account of how Christ unites to the elements, but he sees it as being akin to the Holy Spirit descending as dove—the Spirit visibly and truly came down as the dove yet the Spirit is invisible.
