Over the past few weeks, Pope Francis has been pointing to Saint Joseph as a model. It's the way he's wrapping up a year with an emphasis on the foster father of Jesus. To have an adoptive father in the news who is good -- just -- is no small thing at a time when we have some 440,000 children stuck in the foster-care system. It's also timely with the Mississippi abortion case about to be heard at the Supreme Court. We talk about women when it comes to abortion, as we obviously should, because she is the one who is physically pregnant, tied to the unborn baby within her like no one else on earth. But what about the man? What are his responsibilities? What should we expect of him? What should he be living up to? Saint Joseph helps as a model of guardian who protects mother and child.
