"Today the liturgists ask for this, tomorrow they want something else."
--Canon Aimé Georges Martimort, from the work of the Consilium for the implementation of the liturgical reforms of Sacrosanctum concilium, quoted in Stanislaus Campbell, FSC, From Breviary to the Liturgy of the Hours: The Structural Reform of the Roman Office, 1964-1971.
