Trent and its Liturgical Reform: The Council Debates and Decrees (Part III)

In the first installment of this series, I noted that, along with the standardization effected by the adoption of the Ordo Missae according to the Roman curia, the variety of liturgical uses for dioceses and religious orders continued in the later medieval period. Calls for greater liturgical unification were heard already before the Protestant Reformation. For instance, in 1513, two hermits of Camaldoli, Paolo Giustiniani and Pietro Quirini, made an appeal to Pope Leo X for Church reform, which included the plea for a unified celebration of the Mass and other rites.
