Thanks for the input everyone. I'm sure not all Greek parishes are like mine. I actually think mine is on the extreme end of the anti-social spectrum. We've lost several wonderful, wonderful priests who couldn't take it anymore and left for calmer waters at other parishes. GREEK priests who couldn't take our GREEK parish anymore!
Our assistant priest, who isn't Greek himself, has told us to go wherever we feel comfortable. I just wondered what the official process entails.
I also struggle with the decision because of my kids. I feel like I am depriving them of part of their Greek heritage by removing them from the Greek church. But then I tell myself that God is above all of these ethnic differences and they need to be in a safe, friendly environment where they can focus on God, and not in a Greek place that will potentially ostracize them and make them not want to attend church. One of my half-Greek friends from church is going through this with her 5 year old right now.
