The thing I remember most about St. Mother Teresa, whose feast is Sept. 5, was her joy. I met her three times in my life. Once when we were giving talks on the same program; once at a Vatican Seminar on Family Life, and once when she asked me to give a week-long retreat to her contemplative novices on joy. She founded two distinct orders, the one she picked for me was her cloistered contemplative community in New Jersey.
