Deacon \Dea"con\, n. [OE. diakne, deakne, deken, AS. diacon,
   deacon, L. diaconus, fr. Gr. ? a servant or minister, a
   minister of the church; of uncertain origin. In sense 2 prob.
   confused with dean.]
   1. (Eccl.) An officer in Christian churches appointed to
      perform certain subordinate duties varying in different
      communions. In the Roman Catholic and Episcopal churches,
      a person admitted to the lowest order in the ministry,
      subordinate to the bishops and priests. In Presbyterian
      churches, he is subordinate to the minister and elders,
      and has charge of certain duties connected with the
      communion service and the care of the poor. In
      Congregational churches, he is subordinate to the pastor,
      and has duties as in the Presbyterian church.

Deacon \Dea"con\, v. t.
   To read aloud each line of (a psalm or hymn) before singing
   it, -- usually with off. [Colloq. New. Eng.] See {Line}, v.
   t.

   Note: The expression is derived from a former custom in the
         Congregational churches of New England. It was part of
         the office of a deacon to read aloud the psalm given
         out, one line at a time, the congregation singing each
         line as soon as read; -- called, also, lining out the
         psalm.
