The feast of the Royal Martyrs of Russia in a non moveable feast (i.e. based on the menaion) celebrated always July 4th (Julian Calander). This was the day they were martyred by the communists. It is said that Lenin ordered their murder to be performed on this day as a overture to the U.S. (Some of the money that funded the bolsheviks came from the U.S.).
The Russian Orthodox Church Abroad (which you incorrectly refered to aa ROCOR) under Metropolitan Philaret glorified the Royal Martyrs in 1981. The MP later adopted the same service (troparion, kontakion, Odes for the canon read at matins and other verses). I believe this service for the Royal Martyrs was adopted for use by other Orthodox Churches.
You are correct that the ROCA and MP glorifed different saints; Metroplitan Joseph of Petrograd comes to mind.
OK, sorry for the confusion. The article is about New Martyrs and Confessors of Russia, so the icon is right for the article.
Indeed the MP reluctantly glorified a different set of saints, and they did it differently, replacing “velikomuchenik” (great martyr) with “strastoterpetz” (sufferer of passion), underlying the MP’s skepticism regarding the pedagogical merit of the martyrdom. Is that correct?
