Prayer appears to be the normal way for believers
(saints) on
earth to support one another. Probably all of us
have asked
another Christian, as Paul did--another saint in the
Body of
Christ--to pray for us when we had a need.
Catholic Christians believe that as we can ask a fellow
Christian--a saint--to pray for us, we should be able to ask
prayers from the saints already united to the Lord
in heaven.
