True, every line of the Byzantine Orthodox liturgy served to dramatize the worship of God and the work of Christ. But for several centuries, even the homily itself took on the form and nature of a dramatic performance, an eternal "opera" that drew both clergy and laity into the divine mysteries of the faith. Instead of merely listening to the words of a preacher, all participated in bringing to life the events and Scripture readings for a Sunday or a particular feast day through the chanting of the kontakion, a type of poem that peaked in popularity during the 5th, 6th, and 7th centuries.
C. A. Trypanis, author of a recent survey of Greek poetry, has praised the kontakion as the most singular literary achievement of the Byzantine Empire. It solidified the shift in Greek poetry from classical rules to metrical forms dependent on syllable count and stress accent, an approach more acceptable to the various nationalities that comprised the Eastern Roman Empire. This was in keeping with changes that had occurred in the Greek language during the Hellenistic period. The most beloved hymn of the Greek Orthodox Church, the Akathist Hymn (still chanted today in toto during Lent), is a richly embellished variation on the kontakion.
Even now, though quite abbreviated, the kontakion finds a place in the liturgy of the Eastern Orthodox Church.
Simply put, the kontakion was a "sung sermon." It served to instruct the clergy and laity on the subject of a feast day relating to the life of Christ, His Mother, or one of the saints venerated by the Orthodox Church.
The kontakion's original form consisted of a series of 18 to 30 stanzas written in the same meter. The meters used were based on stress accents and the syllable-count in each line. These stanzas were preceded by a prelude of one to four stanzas, composed in a different meter, that introduced the refrain found at the end of every stanza. This refrain was typically sung by the people. The initial letter of each stanza, when strung together, formed an acrostic that either followed the Greek alphabet, spelled out a simple message, or gave the name of the composer.
One compelling characteristic of the kontakion is its use of dramatic dialogue. The composers did not hesitate to place words in the mouths of their characters. The anonymous Lament of Adam finds Adam beseeching Paradise itself to intercede on his behalf: "O paradise, embrace your now landless landlord/And by the rustle of your leaves entreat our Maker/To keep you open." Romanos' kontakion "On the Victory of the Cross" finds Hades describing his reaction as the cross shatters the gates of hell: "Go on, wake up, Belial," Hades cries, "Run, unveil your eyes and see the root of the tree within my soul." Such imagery heightened the congregation's sense of participation in the cosmic drama of Christianity.
Romanos died in the latter half of the 6th century. Kontakia continued to appear, but at the end of the 7th century a twofold blow hastened its demise in the liturgical life of the Orthodox Church. First, the church council at Trullo in 692 (the Quinisext Council) ruled that priests needed to address the laity directly in their homilies. Poetry would take a back seat to preaching. Second, the increasing influence of Orthodox monasticism in the life of the church led to the kontakion's virtual replacement in the liturgy by the canon, a poetic form more suitable for prayer and contemplation than the operatic kontakion.
