The Akathist Hymn (, "unseated hymn") is a hymn usually recited by Eastern Christians, such as Eastern Catholics, Oriental Orthodox, Assyrian Church of the East, and Eastern Orthodox 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. During Eastern Catholic and Orthodox Christian religious services in general, sitting, standing, bowing and the making of prostrations are set by an intricate set of rules, as well as individual discretion. Only during readings of the Gospel and the singing of Akathists is standing considered mandatory for all. The akathist par excellence is that written in the seventh century to the Theotokos. In its use as part of the service of the Salutations to the Theotokos (used in the Byzantine tradition during Great Lent), it is often known by its Greek or Arabic names, Chairetismoi (Χαιρετισμοί, "Rejoicings") and Madayeh, respectively; in the Slavic tradition it is known as Akafist.
The writing of akathists (occasionally spelled acathist) continues today as part of the general composition of an akolouthia, particularly in the Slavic tradition, although not all are widely known nor translated beyond the original language. Reader Isaac E. Lambertsen has done a large amount of translation work, including many different akathists. Most of the newer akathists are pastiche, that is, a generic form imitating the original 6th-century akathist to the Theotokos into which a particular saint's name is inserted. In the Greek, Arabic, and Russian Old Rite traditions, the only akathist permitted in formal liturgical use is the original akathist.
Usage examples of "akathist".
Of course, a man who writes an akathist has to know the life extremely well, to the last little point.
Moscow, our father vicar graduated from the Kazan theological academy, there are intelligent hiero-monks and elders among us, and yet, just imagine, not a single one of them could write akathists, but Nikolai, a simple monk, a hierodeacon, never studied anywhere and even had no external appeal, and yet he wrote!
Well, and also to follow the other akathists, how to begin and what to write about.
This sympathetic, poetic man, who came at night to call out to Ieronym and who strewed his akathists with flowers, stars, and rays of sunlight, lonely and not understood, I picture to myself as timid, pale, with gentle, meek, and sad features.
