Fr Seraphim Rose himself wrote in his book “Orthodoxy and the religion of the future” (found in the 1983 edition on page 220; in later editions some parts of the following paragraph have “mysteriously” disappeared):
"Unknown to the fevered Orthodox “revivalists,” the Lord has reserved in the world, even as in the days of Elijah the Prophet, seven thousand men who have not bowed the knee to Baal [Rom. 11:4] — an unknown number of true Orthodox Christians who are neither spiritually dead, as the Orthodox “charismatics” complain that their flocks have been, nor the pompously “spirit-filled,” as these same flocks become under “charismatic” suggestion. They are not carried away by the movement of apostasy nor by any false “awakening,” but continue rooted in the holy and saving Faith of Holy Orthodoxy in the tradition the Holy Fathers have handed down to them, watching the signs of the times and traveling the narrow path to salvation. Many of them follow the bishops of the few Orthodox jurisdicitions that have strong stands against the apostasy of our times: the Catacomb Church of Russia, the Russian Church Outside of Russia, the True Orthodox Christians [Old Calendarists] of Greece. But there are some left in other jurisdictions also, grieving over the ever more evident apostasy of their hierarchs and striving somehow to keep their own Orthodoxy intact; and there are still others outside of the Orthodox Church who by God’s grace, their hearts being open to His call, will undoubtedly yet be joined to genuine Holy Orthodoxy. These “seven thousand “are the foundation of the future and only 0rthodoxy of the latter times."
“Do not be deceived !”
“In the end, when critical times come, I think it will be seen how useful it was that there were some [jurisdictions] which stayed behind, and some bishops and priests who stayed in a sort of backward point of view in order to be of help when a crisis comes. Because it is true that many of the Orthodox hierarchs are going much too far in following Rome which is following the Western confessions. It will come to a disaster before very long.” (Hieromonk Seraphim (Rose) at a gathering of an Orthodox student fellowship at UC Santa Cruz, 1981
