“Solesmes Ictus” • Can It Be Justified? (Examples)

“If you begin by telling a man that in a word like 𝐷𝑒𝑢𝑠 the first syllable corresponds to the weak beat, the second to the strong beat of a modern bar, the only thing accomplished will be to bewilder him thoroughly.” —Father Bewerunge

Random Quote

“The authority of the Pope is not unlimited. It is at the service of Sacred Tradition. Still less is any kind of general ‘freedom’ of manufacture, degenerating into spontaneous improvisation, compatible with the essence of faith and liturgy. The greatness of the liturgy depends—we shall have to repeat this frequently—on its lack of spontaneity.”

— Josef Cardinal Ratzinger (2000)
