I'm going as a delegate from my parish to the Ukrainian Orthodox of USA Sobor in October.
They are held every 3 years. We had an "extraordinary" one day Sobor last year, to elect a new Metropolitan, after ours passed away.
3 years ago was my first Sobor and while it was an exhausting 3 days, it was the most uplifting and exciting 3 days! Each parish, in good standing, sends two lay delegates and one clergy.
In addition to the regular agenda, review of budget, etc. , each department gives a report - the Youth Ministry, Sisterhood, Ukr. Orthodox League, etc. Everyone can ask questions, or give comments towards each report...there are special sessions where various topics are discussed. The delegates can pick and choose which one to attend, that has the greatest impact for them and their parish.
There is of course, Liturgy each morning, and Vespers each evening. You get to meet with your own bishops, guest hierarchs, clergy and laity. It's the coolest experience.
I think I smiled the entire 3 days. I got in to the habit of Liturgy at 7:30 a.m. and Vespers at 6. I would wake up for days after I got home, expecting to hurry up and get dressed and run to church. The hotel is located a mere 1/2 mile from the Consistory and church.
When we return, we schedule a session post-Liturgy one Sunday to share with the rest of the parish what we heard, what we learned, what issues were addressed, what positive changes occurred, etc.
If you can go, I highly recommend it. You'll be exhausted, but, you'll be ever so much more spiritually uplifted...
I was sooo excited, that I got nicknamed "Khvora" (Sick)...because I was eager to see and hear everything.
