Can you recommend any online guides/handbooks/manuals for Eastern Rite Orthodox altar servers, please?
Funny you should mention it. We are working a an Alter Servers guide. It's been slow going and it's true that somethings are done very differently in different Jurisdiction. However, we are trying to put something together... Wont be done any time soon. If anyone here has suggestions, please post them or send me a PM.
For now, assist anyone more experienced than you are and remember what they do and when. Then let someone less experienced than you, help you.
