The great Fr. Aris Metrakos of San Francisco's Holy Trinity Greek Orthodox Church gave the invocation at the Walk for Life West Coast this year, and there were quite a number of other Orthodox priests and our Orthodox brothers and sisters there, too. Five Loaves has a post over at Catholic Answers about Orthodox participation, and here is a nice photo of Fr. Aris leading us in prayer:
Bless you, Father! and Thank you!
