"In parishes, where there is a stable group of faithful who adhere to the earlier
liturgical tradition, the pastor should willingly accept their requests to celebrate
the Mass according to the rite of the Roman Missal published in 1962, and ensure that
the welfare of these faithful harmonises with the ordinary pastoral care of the parish,
under the guidance of the bishop in accordance with canon 392, avoiding discord and
favouring the unity of the whole Church."
