In the Byzantine Rite, aside from the Paschal liturgy, when are antiphons other than the Typical Psalms and the Beatitudes used? And what are these alternate antiphons?
Also, the Octoechos contains the antiphonal text that is interpolated with the Beatitudes for each of the Eight Tones. In the Greek parish typikon, however, I understand that the Typical Psalms are usually highly abbrviated or replaced with other brief verses. Where can I find these? I looked in the Orthodox Prayer Book by Fr. Seraphim Nassar, which tends to follow the Greek parish Typikon rather than the Sabaite, but I could find no information on the shortened antiphons now predominant in the Greek tradition, or where they would be found.
Lastly, a question for Salpy, Aram and my other Armenian friends: Given that the Armenian Rite uses basically the same three Antiphons as the Byzantine Rite, even the same prayers, does it also substitute alternate antiphons, for example, on Pascha, and if so, when, and what antiphons does it substitute?
