Dear Brethren in Christ:
I have a question pertaining to the Holy Mystery of Baptism and being a sponsor for this.
I've read alot on how in Byzantine Church canonical tradition, Baptism establishes a spiritaul relationship not only between Godparents and Godchild but also between their families. When a couple becomes Godparents, as a result, their children become spiritual siblings to the other family. Traditionally the Church's canons do not allow marriage between children of families connected through Baptism. I'm not exactly sure how modern Eastern Catholic Church canons deal with this question. Recently a family asked my wife and I to be Godparents. I am concerned that by so doing, I am eliminating the chances of my children being able to marry their children. Perhaps, if it were God's will for this to happen, they could be granted economia (or a dispensation) from this rule. But I wouldn't want to assume this. Canons 808 - 812 in the Code of Canons of the Eastern Churches seem to deal with this question on but I'm not sure if they agree or disagree with the ancient canons which forbid this.
Forgive me if this is the wrong forum for this question and please feel free to move the thread to its proper location.
