St. Martin in the Wall Church, Chalice.
In 1414 Jacob of Mies first served the holy communion under both kinds to laymen (which was forbidden by the Fourth Council of the Lateran in 1215) by the approval of Jan Hus who already dwelt in Constance. Communion under both kinds represented by chalice became the main symbol of the Bohemian Reformation. Up to the present time the chalice is a symbol of non-Catholic Christians in the Czech Republic. St. Martin in the Wall (Czech: Kostel sv. Martina ve zdi) is a church in Prague. Used to mark the boundary between the Old Town and the New Town, its name dates from the time when the church was a part of the town wall during the fortification of the Old Town. Originally a Romanesque building it was renovated in Gothic style twice.Add to Cart Download
