I am the father of 2 altar servers - my son is 15, and my daughter is 13. I am also involved in the training of altar servers in the parish.
As mentioned previously in this thread, boys and girls of this age are quite different (in general) when committing to altar serving. Having my son altar serve is like pulling teeth. He is still scheduled to altar serve a couple times a month, but he would rather not if he had a choice.
My daughter, on the other hand, would serve every week if possible, and she checks before every Mass we attend to see if there are enough altar servers present so she can serve if a scheduled altar server does not show up.
From the altar server training that I run, I can confirm, as a previous poster mentioned, the girls are much more organized, timely, etc. Most of the boys are there because they have to be. The girls truly seem to want to be there.
Again, these are generalities, and will not be true for all.
My daughter couldn’t wait to become an altar server, and she has truly blossomed into a wonderful Catholic girl. For example: when she was in the 4th grade at our local Catholic School, she had befriended an older nun who was extremely active in the missions. My daughter, after receiving nearly $100 for her birthday gifts from family, wanted to give it all to the missions. We talked about it, how noble it was for her to think that way, etc. We also mentioned that the money was given to her for her to get something for herself; but if she wanted to give it to the missions, she could. She ended up settling on giving the missions half of her money, and saving the other half for something she may want. The sister she befriended asked out family to attend the Diocesan ceremony where her school was awarded the top prize for fundraising for the missions for the 8th year in a row. My daughter was glowing throughout the day.
My son would never have even considered the missions. Different people. Different attitudes. Different priorities.
Back to altar serving - the Pope said OK. If the Bishop says OK and the Pastor says OK, and the priest offering Mass says OK, who are we to say “No”? Why is this such a bad thing? Sure altar serving can lead to vocations in boys. Most of the vocations for boys in our Diocese are from boys who were altar servers. That seems to make logical sense though, since most boys that are “good” Catholics are altar servers at that age; whether they all want to be or not
My daughter know full well she cannot become a Priest or Deacon. That doesn’t mean that she shouldn’t be an altar server. She gets truly excited to attend Mass when she is serving, and she looks forward to the possibility of an absent server when she is not scheduled. She looks forward to serving in any way possible. We have numerous past female altar servers now serving as Lectors in our parish.
Isn’t that what we want from our young people - the desire to serve God and His People. I am sure that altar serving has made her MUCH closer to God and her faith!
