… to promote vocations to the priesthood. Decision of rector, not bishop. Females can be sacristan and help set up before Mass, but not minister at the altar.
Rector claims that ministry at the altar is priestly, but I think he’s mistaken. Before Vatican II, ministry of servers (and choir, BTW, though it was largely ignored) was considered priestly and thus not open to females. Since Vatican II, such ministries are seen as lay, and in 1983 the Holy See decreed that females were permitted to be altar servers. It has since been clarified that no priest is required to allow female servers.
