After years of positive but static service in those roles, Vatican II encouraged sisters to look at their historical roots. Many communities once again are pioneering into new fields. Sisters are fighting for social justice. They are shareholders in for-profit firms and bring up economic equality at shareholders' meetings. They demonstrate against the death penalty and other issues, and sometimes even get arrested for their cause.
Most orders also hold special concern for women and children.
Nuns today also have more freedom to pursue their interests and talents. Sisters have input on what service they pursue. In the old days you went where you were sent. I think people are happier. Despite that, nuns say drawing women to religious life is not easy.
