The former prefect of the CDF Cardinal Muller has voiced reservations about Pope Francis’ Magnum principium, which gave national Bishops’ Conferences more freedom in translating liturgical texts.
Translated from Passauer Neue Presse:
Muller expresses reserve about giving bishops’ conferences more freedom in the translation of liturgical texts. The Cardinal says the liturgy should unite and not divide. “The last authority in cases of doubt cannot lie with bishops’ conferences.” Otherwise one could fear that the unity of the Catholic Church in faith, confession, and prayer would be destroyed. . . . The cardinal referred to experiences where bishops have brought in translators who watered down Biblical and other texts under the pretext of better comprehension.
