JKirk,
Although Our Lady of Wisdom is a parish of the Byzantine (Ruthenian) Catholic Eparchy of Van Nuys, it was generously erected by the Ruthenians to serve LV’s substantial community of Byzantine Italo-Greico-Albanian Catholics, who have no hierarchy of their own in this country and only one other organized community (Our Lady of Grace Society), the latter subject to the Latin Archbishop of New York City.
As Vladyka William, the Eparch of Van Nuys, said of it, the Divine Liturgy there is much more like a Melkite Liturgy than a Ruthenian, as it shares the Byzantine Greek Tradition with the Melkites, rather than using the Byzantine Slav Tradition of its Eparchy.
The language you heard was likely Greek, as the community is significantly more heavily Italo-Greek than Italo-Albanian from what I understand. Alternatively, it may have been Albanian. It would not have been Arabic, used only by the Melkites among the Byzantine Rite Churches, or Aramaic, which is used primarily by the Maronites and Syriacs, neither of which use the Byzantine Rite. (There is not a separate Lebanese language; the Lebanese speak Arabic.)
Many years,
Neil
