Evil .... that is the view held by the SSPX of the Novus Ordo mass.
What does that make us, who attend the NO Rite? A rite sanctioned by the Vatican?
PART I. Can women be permitted to sing in the choir in church?
Sorry, Des, it seems you cannot sing at the Tridentine Rite. The principles are given by Pope Saint Pius X in his motu proprio on the restoration of Sacred Music, and in particular of the ancient Gregorian Chant. This document of Nov. 22, 1903, is entitled Tra le sollecitudine and is published in its entirety in the March 1995 issue of The Angelus (pp.36-40).
The Pope states repeatedly that the Sacred Chant is an integral part of the liturgy, directed to the glory of God and the sanctification and edification of the faithful. (§1) It is consequently not a performance, but a part of the act of divine worship. His conclusion follows:
Except the chant of the celebrant and the sacred ministers at the altar, which must always be sung in plainchant without any accompaniment, the rest of the liturgical singing belongs properly to the choir of clerics...It follows from the same principle that the singers in church have a real liturgical office, and that women therefore, being incapable of such an office, cannot be admitted to the choir (§§12, 13).
