It was a common objection of Pagan philosophers that the Christian religion was not founded upon reason but only on faith. Cyril’s answer that faith is necessary in the ordinary affairs of life is the same which Origen had employed against Celsus (I. 11):  “Why should it not be more reasonable, since all human affairs are dependent upon faith, to believe God rather than men?  For who takes a voyage, or marries, or begets children, or casts seeds into the ground, without believing that better things will result, although the contrary might and sometimes does happen?”  See also Arnobius, adversus Gentes, II. 8; and Hooker’s allusion to the scornful reproach of Julian the Apostate, “The highest point of your wisdom is believe” (Eccles. Pol. V. lxiii. 1.).
