Reviewing my parish’s altar server roster yesterday morning, I noticed we have a balance of 47 boys, 47 girls. I encounter more problems with combatative siblings serving together than boys shying away because of girls.
Boys make up about 30% of the younger children’s choir, and one out of thirty voices for the junior high choir. It would be good to improve male participation in the latter.

My parish was directly effected by the abuse scandal. Since then we are struggling to get altar servers of both sexes. We only have a total of 10!!, 6 are girls! The childrens choir is all girls! We’re at a loss at how we can solve the problem. Maybe it will just take a long time.
