The same way, I suppose, that they have felt a call in the past when we had large numbers of young women entering the religious life, at a time when there were no women on the altar.
When I was an altar server—well, back then, it was just altar boys—**there were no lectors, **no extraordinary ministers of holy communion, no cantors, no readers, and no one in the sanctuary but the priest and the altar boys. The choir was in the choir loft, heard but not seen.
Yet there were not only a lot of vocations to the priesthood, there were a lot of vocations to the religious life, with full convents. Then came the drought.
Today there are fewer sisters to provide examples to girls and young women. Yet in this area, there seems to be something of a mini-renaissance happening with regard to religious life. There are several orders of women religious whose members are aging. But we also have a new order of sisters with younger members, and whose charism is teaching. Recently a new order of monastic carmelites moved here. And an annual discernment retreat for young women has been quite successful. Fr. Z recently made mention of a new order of nuns in the Kansas City diocese who are traditional in their devotions and with young membership. So perhaps the tide is turning.
