Akathist
An Akathist, akaphist or Acathist Hymn (Greek: Ἀκάθιστος Ὕμνος, "unseated hymn") is a type of hymn usually recited by Eastern Orthodox and Byzantine Catholic Christians, dedicated to a saint, holy event, or one of the persons of the Holy Trinity. The name derives from the fact that during the chanting of the hymn, or sometimes the whole service, the congregation is expected to remain standing in reverence, without sitting down (ἀ-, a-, "without, not" and κάθισις, káthisis, "sitting"), except for the aged or infirm.
