I should like to ask His Excellency: what does the seal of Michael the Archangel look like, how is the seal to be used, and where can one be obtained? Thank you, and God bless you. In Christ, Theodore.
The seal that appears below is carried for protection, and is used by exorcists when engaged in confronting demons. Like all symbols of this kind, its efficacy lies in the symbol being blessed in the correct manner and, most important of all, the strength of faith held by the person carrying it. Authentic seals are not easily obtainable, and suppliers of esoterica are not to be recommended. Try a traditional Catholic source, and have a traditionalist priest bless it. Without the requisite faith of the user, however, the seal and/or sigil is impotent.
