"if anyone, which God forbid, should dare willfully to deny or to call into doubt that which we have defined, let him know that he has fallen away completely from the divine and Catholic Faith."
After this, to claim that one could possibly expect to find relics of bones from Our Lady at some archeological site would be calling into doubt this dogma.
The same question is asked: could the Apostolic See approve of a catchism for the general public use containing this? And, books for the general clergy? And, the Church having scrutinized the works of a later Saint which has this in it, and approved? And to top it all off, have this usage last for hundreds of years and nobody in the whole Church notice it was calling into doubt the dogma of the Assumption? Is that scenario possible?
Why skip over the question I asked? - not that I expect an answer, but to show that asking you the same question that you asked me - but with a different dogma as subject matter will produce no reply.
But for the sake of getting it over with already - "Apostolic See" is another fine term - why not simply ask if the pope would approve of such things as catechisms and etc. teaching that one could expect to find some bones of Our Lady?
The answer we can safely assume to be true is, no - assuming we are not talking about the Conciliar popes, then the answer is, certainly - it would even be encouraged........come to think of it, I'm a little surprised they haven't launched an expedition already.
For whatever it is worth, you are not asking the right question.
It is more accurate to put it this way:
Would the Church ever rescind the decree defining the Doctrine of the Assumption in order to accommodate all the teachings about claims that one could possibly expect to find relics of bones from Our Lady found in catechisms and other text books for clergy and to agree with great saints who posed the query for 100s of years?
