This glossary originated out of frustration, mainly the frustration of colleagues in the Office of the Public Ministry not having a common vocabulary, a churchly vocabulary, with which to converse. I have had several fieldworkers who respond with blank stares or confusion at such basic terms as pall, corporal, superfrontal and reredos, let alone Laetare, Greater Gloria, or Benedicamus. Nor is this is a new phenomena, because there are ordained clergy serving before their local altars who are little better prepared. Every “trade” has technical terms used to refer to the tools and the processes used by those participating in that trade. The ability to use the historic ecclesiastical and liturgcal vocabulary, and use them correctly is a sign of knowledge, skill, and care. It seems, however, that instead of treating the things of God with greater reverence than the trades of men, many in the Office show a lack of skill and care that would lead to expulsion from a trade union. For those who care, and want to better use the tools of the ‘clergy trade’, this page is here to hopefully serve you.
While some can, and have, devoted whole Wiki pages to a single term, the definitions in this brief, informative, and hopefully concise ‘glossary’ are meant to give a usable starting point for understanding the depth, breadth, and beauty of the Church’s vocabulary. It is my hope that those intimately involved in the Church would certainly and ultimately want to dig deeper and go beyond these brief ‘definitions’.
