I was invited to attend the wedding of a Baptist (groom) and a Russian Orthodox (bride). They are being married in a Lutheran church. They have not contacted a clergyman of the Russian Orthodox faith about their wedding plans. I don’t know much about the Russian Orthodox faith. Should I consider the bride a “Catholic” and not attend the wedding as there will not be a priest present and no dispensation given? The wedding is taking place in the northern Midwest and I do not know if the Russian Orthodox church has a presence here. The bride is from Russia and has been attending the church of her husband-to-be, however, she has not renounced her faith.
Also, if I must decline the wedding invitation, what acknowledgement can I make of this wedding? Can I attend the reception, or send a gift or a card?
