I find this really inappropriate and think that someone should have told him something, even if it was just the Priest in private when everything was over
If it was done in private, then how would you know whether it was done or not?
I never thought of that. Anyway, I mean, the guy should have at least made some effort to dress nicer and think that this is an important event.
a. I'm just glad the guy was in Church. A lot of people weren't.
b. As a 24-year-old grad student with a chronically ill wife and 2 small children, I was just happy I had a pair of jeans without any holes in them to wear to Pascha. And if my one good pair of jeans had gotten ripped at the last minute, which would be more important? Wearing whatever I had available or skipping Pascha because I couldn't dress to people's standards?
c. You don't know what the priest may have said to him. You don't know what his godfather may have said to him. You don't know what 3 other strangers may have said to him. Do you even want to take a chance on being stranger #6 who instead of welcoming him to the Feast, criticized his presence and became the straw that broke the camel's back and caused him never to come back to that unwelcoming church?
d. What is more important, his salvation or what he's wearing? What is more important, you focusing on the prayers or paying attention to what other people are wearing?
Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
If someone asks, it's perfectly appropriate to tell them what you think they should wear. If they don't, it's perfectly appropriate to mind your own business--as in worry about your own salvation.
