2. The Use of Supplemental Liturgical Materials

Supplemental liturgical materials may only be used with the permission of the diocesan bishop or, in the absence of the bishop, of the appropriate ecclesiastical authority. This authorization has a twofold purpose. First, it recognizes and affirms the bishop as the expression of unity in the life of the Church. Secondly, it provides a point of dialogue for the ongoing experience and development of the rites. Liturgical development needs to be done within the purview of the whole Church where there is a framework for theological reflection and dialogue.
