Ecclesiastical Latin continues to be the official language of the Catholic Church. The Second Vatican Council decided to allow languages other than Latin to be used in Mass in order to relate the Church and its values to modern culture. However, the Church still produces its official liturgical texts in Latin, which provide a single clear point of reference for translations into all other languages. The same holds for the official texts of canon law and many other doctrinal and pastoral communications and directives of the Holy See, such as encyclical letters, "motu proprios", and declarations "ex cathedra". Pope Benedict XVI gave his unexpected resignation speech in Latin.
