Bye Bye Vatican II: Latin Is Now FORBIDDEN in Saint Peter’s
This measure is a slap in the face of Vatican II which decrees that "the use of the Latin language is to be preserved in the Latin rites” (Sacrosanctum Concilium, 36). Only the Gloria, Sanctus, Our Father and Agnus may be occasionally in Latin. Whether this will be the case is up to the Prefect or the Master of the Sistine Chapel Choir. The readings and the Prayer of the Faithful may be in various languages - except Latin.
In future, also the Chapter of Saint Peter's will be forced to sing the Liturgy of the Hours in Italian, maintaining the Gregorian melody - which is impossible with an Italian text - and keeping only some parts in Latin: Hymn, Antiphon, Benedictus, Magnificat and Our Father. Latin in the Liturgy of the Hours will be abolished when corresponding Italian booklets are ready.
In the list of world languages by total number of speakers, Italian is on place 27 after Javanese and before Western Punjabi. This measure seems to reflect Francis' personal animosity against Latin because due to his poor theological formation his Latin is also poor.
