   Syn: Awe; honor; veneration; adoration; dread.

   Usage: Awe, Reverence, Dread, Veneration. Reverence
          is a strong sentiment of respect and esteem, sometimes
          mingled slightly with fear; as, reverence for the
          divine law. Awe is a mixed feeling of sublimity and
          dread in view of something great or terrible, sublime
          or sacred; as, awe at the divine presence. It does not
          necessarily imply love. Dread is an anxious fear in
          view of an impending evil; as, dread of punishment.
          Veneration is reverence in its strongest
          manifestations. It is the highest emotion we can
          exercise toward human beings. Exalted and noble
          objects produce reverence; terrific and threatening
          objects awaken dread; a sense of the divine presence
          fills us with awe; a union of wisdom and virtue in one
          who is advanced in years inspires us with veneration.
