The sisters openly promote the illegal form of the Roman Rite.
Current liturgical legislation for Latin Rite Catholics have only one rite, the Roman Rite, but two forms, the Ordinary Form (the Missal of Ven. Paul VI, with the addition of the name of St. Joseph to the four anaphoras (Eucharistic Prayers) by the reigning pontiff, Francis) and the Missal of St. John XXIII also known as the Extraordinary Form.
Apart from the indult granted for the Diocese of Zaire or now known as the Zaire Use or Roman Missal for the Dioceses of Zaire, and the Anglican Use for the Anglican Ordinariate and other limited use rites, nowhere will you find a document giving the Misa ng Bayang Pilipino permission to be celebrated.
the Misa ng Bayang Pilipino is ILLEGAL!
And anything done illegally, is IMMORAL.
