In practice, when people from different faiths come together to be at prayer together, it is not to engage in a formal and communal act, but to listen and to learn as each delegation prays in its own way. It is an act of dialogue in which people of faith bring their forms of prayer, their scriptures and their most valued spiritual traditions together in an act of faithful common witness. It is precisely as the word "interfaith" implies, a meeting between people of faith.
