I took a lot of time finding out the answer to this question, in large part because of you, Aramis, but I finally have the answer thanks to a friend of mine who was baptized Episcopalian (obviously Latin in tradition, then - less ambiguous than my baptism, through a non-denominational charismatic church), and chrismated Ruthenian Catholic.
Father Robert Pipta, the vocations director for the Eparchy of Phoenix had this to say to a friend of mine who asked the question:
“In asking our Bishop to guide us to clarification on this matter, he
responded in an e-mail (a few years ago now) that his interpretation is
that if one is Chrismated as part of his being received into the Catholic
Church from a non-Catholic denomination, then he becomes canonically a
member of the ritual church in which he is Chrismated.”
As far as Bishop Gerald is concerned, any Protestant who is received into the Catholic Church by the Eparchy of Phoenix is canonically Ruthenian Catholic.
I am afraid that I have to go with my bishop on this one, as opposed to Fr. Gallaro.
