early 14c., from Anglo-French vicare, Old French vicaire "deputy, second in command," also in the ecclesiastical sense (12c.), from Latin vicarius "a substitute, deputy, proxy," noun use of adjective vicarius "substituted, delegated," from vicis "change, interchange, succession; a place, position" (from PIE root *weik- (2) "to bend, to wind"). The original notion is of "earthly representative of God or Christ;" but also used in sense of "person acting as parish priest in place of a real parson" (early 14c.).
The original Vicar of Bray (in figurative use from 1660s) seems to have been Simon Allen, who held the benefice from c. 1540 to 1588, thus serving from the time of Henry VIII to Elizabeth I, being twice a Catholic and twice a Protestant but always vicar of Bray. The village is near Maidenhead in Berkshire.
"doctrines, customs, ceremonies, etc. of the Pope or the Roman Catholic Church," 1530s, a hostile coinage of the Reformation, from pope + -ery.

1610s, "state of celibacy" (especially as mandated to clergy in the Catholic church) from French célibat (16c.), from Latin caelibatus "state of being unmarried" (see celibacy).

"one who advocates the contrary side," 1760, translating Latin advocatus diaboli, in the Catholic Church, a promoter of the faith and officer of the Sacred Congregation of Rites whose job it is to urge against the canonization of a candidate for sainthood. "[F]ar from being the whitewasher of the wicked, the [devil's advocate] is the blackener of the good." [Fowler]. Said to have been first employed in connection with the beatification of St. Lorenzo Giustiniani under Leo X (1513-21).
or Douay, name of town in northern France, used elliptically in reference to the English translation of the Bible begun there late 16c., sanctioned by Roman Catholic Church.

The place name is from the Gaulish personal name Dous + Gallo-Roman -acum.
