The RC church decides about Jesus? You mean outside of church doctrine? Heavens to betsy, no!!! Seems like every church has something to say about JC, from the "Son of God" and "Virgin Birth" bits to the Mormons' "physical son of God and an unnamed woman, conceived by actual intercourse."

Besides, who'd listen?? The majority of Catholics in the Western world don't believe
everything the Vatican says anymore, and certainly those "heretical" Protestant churches wouldn't.
