According to Archimandrite Ephrem (Lash), both in his article “Byzantine Hymns of Hate” in the book Byzantine Orthodoxies (ed. Fr. Andrew Louth and Augustine Casiday) as well as on his website of liturgical texts, the hymnody for the Sunday of the Holy Fathers of the Fourth Ecumenical Council is by Philotheos Kokkinos, a 14th century Patriarch of Constantinople. The Greek text, as Fr. Ephrem says in “Hymns of Hate,” notes in the rubrics the presence of “Philotheos” as an acrostic in in the Theotokia of the Canon at Matins.
So why aren’t these texts contained in the critical edition of his poetic works, which appears to contain all the rest of his hymnody? Where can I find this Petroula Kourtesidos to ask?
