I'm in the uncomfortable position of seeing both sides of this issue. While I think that demanding payment for "services rendered" is certainly simony and to be deplored, parishes have to pay the light bill and priests (and their families!) have to eat.
Where is that money coming from?
If I have to put a donation in the box for candles, I'm ok with that. After all, my parish is paying for the candles, and at .25 each, I don't think it's a major source of income, though I could be wrong.
I do have a problem also with a posted list of payments. But then again, in countries where priests don't receive much in the way of salaries, and the church is recovering from many years of oppression, perhaps a list of "suggested donations" is not too far out of line, in order to inform.
If my daughter were getting married, or the like, I would certainly want to know what would be considered a proper gift or honorarium for the priest, to show my appreciation and gratitude - even though that is, to a certain extent, his job. I would also consider it reasonable to pay some sort of building use fee, since we would be using utilities etc. and someone would have to set up and clean up afterward.
That said, most Orthodox come from countries where there is some sort of state-supported Orthodox Church, so that we do need to work on communicating the concept of tithing and real stewardship, which is how parishes and priests are supported in the US.
Also, as my priest has pointed out, everyone can give something. Btw, we don't pass the hat- we only have a box by the steps that you can drop your offering in. But Father is adamant that everyone should be giving something to support their church.
(To the OP, however, and please forgive me if I have misunderstood - I sincerely apologize in advance if I have got this wrong - from your posts, I get the feeling that, perhaps because of your financial circumstances, this is a chink in your armor. Although you are certainly reasonable to be concerned, I just get the idea that this may be your weak point, that the devil may be exploiting to destroy your peace of mind and your joy in your journey.)
