When it comes to abortion, euthanasia, and other sanctity of life issues, we should not suppose that our choice is between reforming the law and working to change the culture. We must do both. The work of legal reform is necessary, though not sufficient, ingredient in the larger project of cultural transformation. Yes, we must change people's hearts. But no, we must not wait for changes of heart before changing the laws. We must do both at the same time, recognizing that just laws help to form good hearts, and unjust laws impede every other effort in the cause of the Gospel of Life.
