For the feeding and fanning of that ardent love by which, under a law like that of gravitation, we are borne upwards or inwards to rest, the presentation of truth by emblems has a great power: for, thus presented, things move and kindle our affection much more than if they were set forth in bald statements, not clothed with sacramental symbols. Why this should be, it is hard to say; but it is the fact that anything which we are taught by allegory or emblem affects and pleases us more, and is more highly esteemed by us, than it would be if most clearly stated in plain terms. I believe that the emotions are less easily kindled while the soul is wholly involved in earthly things; but if it be brought to those corporeal things which are emblems of spiritual things, and then taken from these to the spiritual realities which they represent, it gathers strength by the mere act of passing from the one to the other, and, like the flame of a lighted torch, is made by the motion to burn more brightly, and is carried away to rest by a more intensely glowing love.
