(3.) The word rationale is also the name of a treatise explaining the meaning, and justifying the continuance, of that ceremonial which it was thought fit to retain in the Church of England in the year 1541. The members of the committee to whom this subject was intrusted were warmly attached to the splendor of the Roman ritual, and, of course, made few alterations. The collects in which prayers were offered for the pope, and the offices for Thomas a Becket and some other saints, were omitted; but so slight were the changes introduced that in many churches the missal and breviary already in use were retained. The Rationale Divinorum Officiorum of Durand, bishop of Mende, written in the latter part of the 13th century, gives the “reasons” of the forms and ceremonies of Romish worship. See Collier, Eccles. Hist. v, 106; Burnet, Hist. of the Ref. 1, 63; Riddle, Christian Antiq. (see Index).
