Prayer and the Community
It is not safe to pray alone. Tradition insists that we pray with, and as a part of, the community, that public worship is preferable to private worship. Here we are faced with an aspect of the polarity of prayer. There is a permanent union between individual worship and community worship, each of which depends for its existence upon the other. To ignore their spiritual symbiosis will prove fatal to both.
