Hey Orthodox11, Gebre, PrincessMommy, katherineofdixie, KBN1, Witega, biro, JamesR, Marat, LBK, ialmisry...thanks so much for your advice and kind words.
KBN1, you're right, I was overthinking things too much! I went to the service, and it was fine. It was a public holiday weekend in New Zealand, so fewer people than usual were there. The priest's wife invited me to sit with her, helped me to follow the liturgy and explained little bits here and there as it unfolded. The priest welcomed and introduced me to the congregation just after the sermon, and briefly explained that only baptised Orthodox Christians could partake of communion, but I was welcome to come forward for some blessed bread at the end of the service. I didn't cross myself or anything, but just participated as best I could while trying to take in all the detail and what was happening around me. I did go up for the blessed bread when the priest invited everyone to do so. Afterwards, the priest explained a little bit about the liturgy and what each part symbolises.
You know how people say on this forum that you've got to go to divine liturgy to really experience and *get* Orthodoxy? They are right, absolutely right. I didn't have a chance to read through the Liturgy of St John Chrysostom before going, so a lot of it went over my head because of unfamiliarity, everything else happening during the service and tiredness from a long weekend and travelling. After I got home, I read through it, plus some Orthodox prayer links others have given me through the forum. Talk about blown away...THIS is worship, in spirit and in truth. I know a bit about Orthodoxy from reading books, internet articles and this forum, but the beauty and Christ-centredness of the liturgy and prayers resonated on a deeper level than anything else I've read so far. I know now Orthodoxy is where I want to be, just the opportunity and timing is up to God. I want to go to another service as soon as circumstances permit. So now I'm asking myself, how to move forward from here?
Thanks again everyone
