Christian tradition calls this the communion of saints. Whenever we pray, we pray in community. This is why some prefer to speak of "personal" rather than "private" prayers. But that won't get us far. What is the alternative to personal prayer? Impersonal prayer? Let us hope that there is no such thing. Still, we do need to distinguish between praying together with others and praying by ourselves. I will call these two areas prayers together and prayers alone.
