This sounds like something cooked up in an effort to explain why Catholics were being allowed to venerate a schismatic/heretic as a saint. Especially in the years before V-II that sort of thing would have raised a lot of eyebrows.

I think you may be on to something here. It is my understanding that Gregory of Narek was not included in the Roman Martyrology until 2005. Prior to VII, he is not to be found in the Roman Martyrology of the Catholic Church.

It is my understanding that Gregory of Narek was not included in the Roman Martyrology until 2005.

"The cult of St. Gregory of Narek will be marked on 27 February in the Roman Martyrology. He will be defined as “monk, doctor of the Armenians, distinguished for his writings and mystic science”."
