Analysis of information sources in references of the Wikipedia article "Second Vatican Council" in English language version.
Four hundred years after the Reformation, Vatican II reversed all this and decreed that the assembled people of God celebrate the liturgy; that the texts of worship may be translated into vernacular languages; that the assembled people could drink from the communion cup; that the reading of scripture was to be an essential element of all worship; and that the Eucharist was to be regarded as the source and summit of the Church's life: Ubi Eucharistia, ibi Ecclesia – wherever the Eucharist is, there too is the Church. Such a view was entirely alien to pre-conciliar Roman theology which was more comfortable with the idea: 'Wherever the Pope is, there too is the Church.' Much of this was entirely consonant with Protestant sensibilities and explains why Vatican II was a milestone for Catholic, Protestants, the Orthodox, and all religions.
