That Pic is of my youngest Alexander "The Great" as he calls himself, my background is Macedonian but I am 3'rd generation, my grandfather came to the US in 1902 then to Canada in 1906, both he and my father returned and fought in WWII in the Greek resistance against the Germans and during the Greek revolution against the communists.
We are for the most part Apostolic Christians (our priests can marry but not our bishops), similar to Roman Catholic but not quite as literal in biblical interpretation in fact we are sometimes referred to as Eastern Catholics, oh I forgot we also celebrate holidays by the Julian calendar, Christmas is 2 weeks later and Easter, the more important holiday for us (we BBQ a lamb on a spit after our 40 day fast), closer to the Jewish Passover.
The Church of the Holy Sepulture (a Greek Orthodox Church) is built where Christ is supposed to have been entombed.
Even though I am a Christian I am very understanding of others beliefs and if you think about it real hard (I would also suggest that those of you that are interested read the Torah and the Koran) all 3 of the monotheistic religions are very very similar.
The Hindus have an interesting concept of God, they believe in only one God but that he shows himself in different forms (each form relates to specific groups) to different people hence the impression (and it is only an impression) of a plethora of deities.
If you eat in resaurants you have probably met Greeks and Macedonians, it seems most went into the resaturant business.
Hope that helps.
