The oracles which the Deity has revealed to the nations through His
different mediums, are they clear? Alas! there are not two men who
understand them alike. Those who explain them to others do not agree
among themselves; in order to make them clear, they have recourse to
interpretations, to commentaries, to allegories, to parables, in which
is found a mystical sense very different from the literal one. Men are
needed everywhere to explain the wishes of God, who could not or would
not explain Himself clearly to those whom He desired to enlighten. God
always prefers to use as mediums men who can be suspected of having been
deceived themselves, or having reasons to deceive others.
