The Focolare Movement stands at the forefront of the Catholic Church's efforts to build unity with other religions. One of its key leaders is Roberto Catalano, the director of Focolare's International Office for Interreligious Dialogue. Having lived in India for 28 years, Catalano has facilitated dialogue between Christians and Hindus, as well as conferences with Muslims, Buddhists and Jews. Witness host Fr. Thomas Rosica speaks with Catalano about the pressing need for interreligious dialogue today.
