If that were true, y'all wouldn't feel the need to post threads and come on them so much to state hundreds of times how all the Protestants "vandals" are wrong, heretics, not Christians, blah, blah, blah, yada, yada, yada. In fact, if it really were of no concern, it would not have been made a mandated article of faith for all Christians. AND it would have been something the Apostle John would have at least mentioned if it were so important a belief for the church seeing as he supposedly cared for Mary until her death.
As it is, all you have is legends, myths, hypotheses, dreams, wishes and coulda, shoulda and wouldas to back up some of these extra-biblical stories. I'll stick with the faith God ensured we would know about because He included them in Holy Scripture.
