“ Hence fear may be considered in two ways. First, inasmuch as the sensitive appetite naturally shrinks from bodily hurt, by sorrow if it is present, and by fear if it is future; and thus fear was in Christ, even as sorrow. ”
 Thomas Aquinas, Summa Theologica (1274). copy citation

“Hence the Philosopher says (Rhet. ii, 5) that we do not fear a thing unless there is some hope of avoiding it. For when there is no hope of avoiding it the evil is considered present, and thus it causes sorrow rather than fear. Hence fear may be considered in two ways. First, inasmuch as the sensitive appetite naturally shrinks from bodily hurt, by sorrow if it is present, and by fear if it is future; and thus fear was in Christ, even as sorrow. Secondly, fear may be considered in the uncertainty of the future event, as when at night we are frightened at a sound, not knowing what it is; and in this way there was no fear in Christ, as Damascene says (De Fide Orth. iii, 23) .
