Dear Friends,
When I attended the Antiochian Western Rite conference here some years ago, this prayer was raised - it appears that the Patriarch of Antioch insisted his Western Rite charges include it in their western Liturgies!
The bishop present said this pointed to the particular care of and love for the Western rite that the Patriarch has for the Western Rite Orthodox.
Others whispered that it was blatant "Easternization . . ."
It was a fascinating experience that - the Western Rite Orthodox were actually deriding Eastern traditions (i.e. "icons with the big eyes") and evinced every bit of the "minority complex" that we EC's traditionally have with respect to the RC's!
