The simplicity and the interiority of the liturgical life of the Apostolic Sisters of Saint John are meant to manifest the primacy of silent prayer. That is why in their liturgical chant they strive to give the first place to the proclamation of the Word so that it may lead to the silence of adoration. Their liturgical chant was composed by Magdalith (born in 1932). Of Jewish origin and an adolescent convert to Catholicism, she had a great passion for Gregorian chant and biblical canticles. Later in her life she composed a liturgical repertoire in which she sought to preserve “monody” (one single voice) and the Gregorian modes all the while adjusting them to the French language.
