Luther affirmed a theology of the Eucharist called Sacramental Union, In the sacramental union the consecrated bread is united with the body of Christ and the consecrated wine is united with the blood of Christ by virtue of Christ's original institution with the result that anyone eating and drinking these "elements"—the consecrated bread and wine—really eats and drinks the physical body and blood of Christ as well. Luther wrote about this on multiple occasions, such as in his 1526 "The Sacrament of the Body and Blood of Christ—Against the Fanatics" and his 1528 "Confession Concerning Christ's Supper". In the 1530 Augsburg Confession, the Lutheran position as stated in "" earned the Catholic response in the "Confutatio Augustana" that "The tenth article gives no offense in its words." although later on the Council of Trent would codify transubstantiation as it is taught today and reject the sacramental union.
