In 1521 the university had condemned Luther's Babylonish Captivity, and in 1527 Erasmus's Colloquies met with the same fate.
It was not, however, until 1520 that Luther became in a sense the leader of the German people by issuing his three great pamphlets, all of which were published in German as well as in Latin - his Address to the Christian Nobility of the German Nation, his Babylonish Captivity of the Church, and his Freedom of the Christian.
In addressing the German nobility Luther had refrained from taking up theological or religious doctrines; but in September 1520 he attacked the whole sacramental system of the medieval Church in his Babylonish Captivity of the Church.
This change was a prelude to the more or less complete subjection of the papacy to French influence which took place in the following century at the period of the " Babylonish Captivity," the violent reaction personified by Boniface VIII.
It was the beginning of the long "Babylonish captivity" of the popes.
