The Church is the Body of Christ, and as such it is both heavenly and earthly. The Church is the communion of saints, and it includes as members both angels and shepherds - cherubim and seraphim, and you, and me. - Scott Hahn
The Bible talks primarily of two kinds of angels- Cherubim and Seraphim. But there is a third kind of angel. If you ever find yourself troubled, suffering or in despair, God may send you this third type of angel. These angels are called...'friends. - José N. Harris
