Questions about the ceremonies of the Mass, answered in Adrian Fortescue's own words from The Ceremonies of the Roman Rite Described (1917) and The Mass: A Study of the Roman Liturgy (1912), with a citation for every quotation.
Fortescue describes the Roman rite of his day. Where your parish's Western Rite Orthodox directives differ, follow those. Quotations come from scans of the original editions, so check the scanned page for anything that matters.
