“The idea of birth through a Holy Spirit, of the death of a divine being, of the forgiveness of sins, or the fulfillment of prophecies, are ideas which, any one can see, need but a touch to turn them into something blasphemous or ferocious. The smallest link was let drop by the artificers of the Mediterranean, and the lion of ancestral pessimism burst his chain in the forgotten forests of the north… Here it is enough to notice that if some small mistake were made in doctrine, huge blunders might be made in human happiness. A sentence phrased wrong about the nature of symbolism would have broken all the best statues in Europe. A slip in the definitions might stop all the dances; might wither all the Christmas trees or break all the Easter eggs. Doctrines had to be defined within strict limits, even in order that man might enjoy general human liberties The Church had to be careful, if only that the world might be careless.”— Chesterton
Just try to imagine the dire consequences of an unintentionally ambiguous or misworded doctrine.
