Hi GenuineFarmGirl ---- It's probably a good thing if you respect that the Orthodox church is the Christian flavour that people in Eastern Europe prefer.
It kind of gets to me with evangelical Christians who try to evangelise people who are essentially already Christian, when there are plenty of atheists to target. Although it's "different", all the key elements to Christianity are present in Orthodox Christianity, and it actually happens to be the church that can trace its roots most immediately back to Paul (historical fact).
I can totally sympathise how people in Eastern Europe find that, starting in the 1990s, they were literally invaded by anything from foreign missionaries, to foreign corporations, culture etc to tell them how to live... and buying up a resources at bargain basement prices in the 90s.
So I think the members here are right to advise you to at least be very sensitive.
Imagine if your country was suddenly totally overwhelmed by another country, for example, China, sending missionaries, buying up companies, spreading their culture, their language their way of life and religion.
Hope you'll have a lovely time though, and manage to make some difference in someone's life.
