I am RC, and whenever i had a metal or rosary to be blessed, even if it was after Mass, I would go up to the priest and ask for his blessing. It could be very quick, like the sign of the cross, and a short prayer, or a bit longer. But, they always seemed happy to do so.
So, maybe I'm wrong to assume a blessing for a prayer rope, etc...in the Orthodox Church can be done that way, too.
Sometimes I speak, and should really do the research first!
Also, could the moderator delete my post about being upset with Jennifer's priest? It reads much harsher than it was meant to read, and I don't feel good about it. He is a priest afterall, and I don't want to be disrespectful.
