Cardinal Walter Brandmüller, the 97-year-old German church historian and former president of the Pontifical Committee for Historical Sciences, has issued an appeal for peace in the liturgical disputes, urging all sides to “lay down your weapons”.

Writing in Diakonos on February 24, His Eminence insisted that it was not the Council’s Constitution on the Sacred Liturgy, Sacrosanctum Concilium, that caused the deep rift across much of the Catholic world, but “the implementation of the liturgical reform after the Council”.
