Dear Stephen,
As for the rosary, there is an Old Believers' site (
www.synaxis.net [
synaxis.net]) where there is an article in Russian where the Old Believers say it is "permissible to refer to our Lestovka as either "chotki" or "rosary."
But "rosary" is not only not used in the East in general - it was also not the preferred usage among RC saints who promoted it, including St Dominic.
I don't believe it matters what kind of counter one uses in praying the Rule of the Mother of God, there is also no agreement on this in the East.
It basically consists of 15 decades or "desiatky" as the Encyclopaedia of Orthodoxy published at Moscow in 2003 calls them.
Each is headed with an Our Father, followed by 10 Hail Mary's (St Seraphim added the prayer "Open to us the doors of Your Mercy . . .") and a set of 15 aspects of the life of Christ and Mary are offered - these can and do vary and today in RCism one may come up with any series of meditations - my collection has gone from 15 to 50.
This prayer is never celebrated in Russian Orthodoxy as a liturgical service, but it IS prayed in certain monasteries by groups of monks and nuns.
At Diveyevo Monastery, the nuns go around the monastery reciting the Rule out loud and on feastdays they actually sing the 150 Rejoice O Theotokos prayers.
Is the Rule the same as the Western Rosary? In form and substance it is IDENTICAL. The way in which it is prayed varies not only from East to West, but in various locales in both as well.
The Orthodox are now familiar with the term "rosary" and even the Old Believers have said they find it a legitimate name for their own Lestovka or "prayer step-ladder" which is also very much like the Western "ladder-rosary."
The Old Believers also have TWO types of Lestovkas, the usual one that is associated with the Jesus Prayer and one which is 100 or 150 smaller steps divided every ten with a larger "babotchka" called the "Bogarodychnaya Lestovka" or the Lestovka of the Mother of God.
