"Built of Living Stones" (hereafter: BLS) a document of the USCCB, proposing to set guidelines for the construction of churches in the United States. It, as it note itself, has no binding authority. It does however contain quotes from binding sources, namely the liturgical books, the GIRM, and Canon Law.
It is important to note that this document contains nothing expressly forbidding the traditional arrangement of the Church, on the contrary it includes the mandates for the Tabernacle to be in a noble and visible place, for the sanctuary to both exist and be distinguished from the nave, and for the various liturgical furnishings to be in their proper places.
In spite of this,Fr Vosko claims to use it as a foundational document in his plans that invariably involve making the sanctuary as unnoticeable as possible.
