Charry was on the faculty of the
Perkins School of Theology at
Southern Methodist University from 1992 until 1997. She is the Margaret W. Harmon Professor of Systematic Theology. Charry has served on the editorial boards of
The Christian Century,
Scottish Journal of Theology, and
Pro Ecclesia and edited
Theology Today from 1997 to 2004. Charry's research has focused on how religious commitments and theological convictions contribute to human flourishing, and interfaith understanding between Judaism and Christianity. She has written on
Christian doctrine, moral formation, and the intersections between
theology and
psychology. She says that Christians have been averse to happiness, and argues that thinking about happiness is both consistent with Scripture and represented in ancient Christian thought. Her book
God and the Art of Happiness coins the term "asherism" to refer to a happiness that is found in "the pursuit of an excellent way of life in community." Combining her own personal experience with
Judaism and
Christianity with her philosophical thinking, she has written about the need for both Jews and Christians to overcome their differences and "help each other straighten out their own tradition." ==Personal life==
