Many thanks for that beautiful reply.
You do yourself an injustice, your prose is wonderful and I think all Christian readers will understand the difficult to explain feelings you describe.
Personally, I get the same feeling from attending Catholic mass in different parts of the world, sometimes Latin rite, sometimes Eastern rite. I also get it from attending Orthodox services (do you call it mass, despite my knowledge of Orthodox Christianity I don't actually know if you call it mass). This comes from the fact that Orthodox Christianity goes back 2000 years to the Apostles and I can feel that in the liturgy.
I do not not get that feeling from protestant services, maybe a bias as I am a convert from evangelical protestantism, but I know Catholics that love attending protestant services. Even they, though, will say that one thing is missing, one thing is always missing that can only be found in Catholic and Orthodox services, the real presence.
I have learnt a lot from this forum. Much more than other forums that always (and I mean always) end up descending into a slanging match between Christians and atheists or Catholics and Protestants) so I hope no one will mind if I keep posting here.
I am not of your denomination, but I hope it prospers and grows.
Also, I could do with Orthodox contacts as I am training to be an RE teacher (that's religious education for the non-UK readers on here, a subject that seems to be unique to the UK. All our school children must learn RE and be taught about all the major religions. I have just finished the first of 2 school placements. In five different classes I asked "What are the three major groups that Christianity is split into?". I eventually got Catholics and Protestants, and other replies such as Jews, Anglicans, Muslims, atheists, Mormons, Jehovah's Witnesses. No one said Orthodox. 300 million Orthodox but it seems no one in the UK has ever heard of you) so it would be useful for me to have Orthodox contacts.
