symbol, sb.[1] Also 6 simbole, 6-7 symbole, -boll, 7 simbol; also in L. form. [ad. late L. symbolum (partly through Fr. symbole, 16th c. = Ital., Sp. sim-, Pg. symbolo), a.

1 a A formal authoritative statement or summary of the religious belief of the Christian church, or of a particular church or sect; a creed or confession of faith, spec. the Apostles' Creed. This use is traceable to Cyprian, Bishop of Carthage (C. 250), who applies L. symbolum to the baptismal creed, this creed being the `mark' or `sign' of a Christian as distinguished from a heathen. The notion, long current, that the creed was so called because it was `put together' by the Apostles is without foundation in fact. 1450-1530 Myrr. our Ladye III. 312 Thys crede ys called Simbolum, that ys to say a gatherynge of morselles. for eche of the 1490 CAXTON How to Die 4 The credo and symbole of the fayth. 1536 HEN.
