On 7 July 2007, Benedict XVI issued the "motu proprio Summorum Pontificum", declaring that upon "the request of the faithful", celebration of Mass according to the Missal of 1962 (commonly known as the Tridentine Mass), was to be more easily permitted. Stable groups who previously had to petition their bishop to have a Tridentine Mass may now merely request permission from their local priest. While "Summorum Pontificum" directs that pastors should provide the Tridentine Mass upon the requests of the faithful, it also allows for any qualified priest to offer private celebrations of the Tridentine Mass, to which the faithful may be admitted if they wish. For regularly scheduled public celebrations of the Tridentine Mass, the permission of the priest in charge of the church is required.
