This page is offered as a resource for those interested in the promotion and preservation of the Sacred Triduum of the “older liturgical tradition” (n. 33, Universae Ecclesiae, the instruction on the application of the Apostolic Letter Summorum Pontificum). During his Easter Vigil homily in 2011, Pope Benedict XVI spoke of traditional Holy Week as “before the reform [when] there were twelve Old Testament readings,” helping us to more clearly understand the reference to “older liturgical tradition” in Universae Ecclesiae. While some may argue that this reference was not the intent of that document, the reform of the Holy Week liturgies promulgated in 1955 was clearly not traditional, but served as a transitional liturgy that was experimental at best. Pope Paul VI, in his Apostolic Constitution of the Roman Missal, demonstrates this openly: "It was felt necessary to revise and enrich the formulae of the Roman Missal. The first stage of such a reform was the work of Our Predecessor Pius XII with the reform of the Easter Vigil and the rites of Holy Week, which constituted the first step in the adaptation of the Roman Missal to the contemporary way of thinking.” These “contemporary way of thinking” adaptations frequently broke from ancient practices which deeply expressed the meaning of the rites themselves, replacing traditions passed down to us from ancient times. Since these unprecedented innovations eliminated or obscured traditional meaning, they directly impacted the root of Catholic liturgy and thus potentially the lex orandi, lex credendi of both the faithful and the clergy.
