128 Along with the revision of the liturgical books, as laid down in Art. 25, there is to be an early revision of the canons and ecclesiastical statutes which govern the provision of material things involved in sacred worship. These laws refer especially to the worthy and well planned construction of sacred buildings, the shape and construction of altars, the nobility, placing, and safety of the eucharistic tabernacle, the dignity and suitability of the baptistery, the proper ordering of sacred images, embellishments, and vestments. Laws which seem less suited to the reformed liturgy are to be brought into harmony with it, or else abolished; and any which are helpful are to be retained if already in use, or introduced where they are lacking. According to the norm of Art. 22 of this Constitution, the territorial bodies of bishops are empowered to adapt such things to the needs and customs of their different regions; this applies especially to the materials and form of sacred furnishings and vestments.
