No one quite seems to know how or why this imbalance has occurred.
Alright, I admit it. It was me. I did it. It was all my fault. It started as a little joke to see what I could sneek by the Curia, and it got out of hand when it made it into Canon Law.
Blame me, I'm very sorry. Mea culpa, mea culpa, mea maxima culpa!
Incidently, I'm ethnically Armenian and Irish, Baptized Latin, mother's side is secular (ethnically Armenian, but two generations without the Faith in my particular line), so I'm a true-blue Armenian Latin Catholic with no hoops or anything.
On the other hand, I know a fellow who is two-generations practicing in the Latin Church, but his family is Ukrainian Catholic patrilineally. Wouldn't have even come up as an issue, except he entered the Dominican Order and they did a careful background check and found out that he's "technically" Ukrainian Catholic. The Order went "by the books" and he had to get permission from "his" Ukrainian Catholic Bishop to enter the Order (mind you he had already almost completed his first year of the Novitiate by this point). Long story short, he's now in-line to be a Latin-raised Ukrainian Dominican, bi-ritual and all since he wasn't required to switch Churches in order to enter the Dominican Order, just receive permission from his Ukrainian Bishop.
The upside to all this silliness is that he has a new found appreciation of the Byzantine East, and is bringing it with him into the Dominican Order. I hope to follow in his footsteps some day, God willing!
Peace and God bless!
