This is an interesting thread or could be one.
Exacly. And thanks to everyone who up to now has attempted to make it an interesting thread. I agree; the best thing about my original query was in its being
potentially interesting. Not
actually interesting; just potentially so.
When I said I would like to have the “why” I meant the same thing as desiring the argument. As in, “argument” in the technical sense. That is, what are the
reasons offered by those in the Church for introducing female altar servers? Why is/was it a good idea?
Why permit it, in other words?
I really am drawn to the aspect of our Church that makes it so reasonable and so public. That is, the Holy See rarely (if ever) just comes down in dictate form to the people and says
“We will now do X…and that’s that! So, you want the reason for X? It’s because we say so!!” Our beloved Church gives reasons for its actions.
So, I was assuming that some here might be able to give some of the reasons (or arguments) for why having female altar servers is such a good idea. It looks peculiar to me; to say the least. And I had thought that a woman’s inability to receive the sacrament of Holy Orders was reason enough to have, if any children at all as servers, only boys. I can follow that line of reasoning. It is sensible.
Another poster said that it’s questionable that having boy altar servers is a great way to increase vocations. I would probably tend to agree, if there is not much else spiritually going on in that boy’s life. That would be equivalent to saying that sending my child to 1 hour a week PSR catechism class is enough to teach him the Catholic Faith.

Ha! I don’t think so.
But, even though several have replied here (and I thank you for it) I still feel deprived of those reasons for having female altar servers. When there is at least one
prima facie argument against the practice–to wit, that they will never serve at the altar as adults–it makes the practice at least peculiar. I don’t know how to get around that.
So, if anyone (e.g., an advocate of the practice) has any more to present I’d love to hear it. Is the Vatican document calling for the permissibility of the practice a few years ago posted on the Internet? Perhaps on Vatican.va? I can’t find it, if it is.
