Wednesday morning as I was getting things together for the Lenten noonday service, I noticed that our decanter of Holy Water was almost empty. So, after filling it, I said the prayers below over the water making the sign of the cross where indicated.
Sunday morning during communion and prayer ministry, I gave someone a small bottle of Holy Water and said, "This should solve the problem." Over the years I have seen Holy Water cleanse rooms, attics, garages, entryways etc. (Ask Canon Christopher). It beats 409.
The prayers below come from an old MANUAL FOR PRIESTS. They are, indeed, a recipe for Holy Water. We use them, along with prayers for the exorcism and blessing of salt, when we do a house blessing.
It's not the only thing used for cleaning a temple, and physical space temples are not the only temples in need of cleaning, but it is a good place to begin.
Let us pray. (Exorcism of the water) I adjure thee, O creature of water, in the Name of God the Father + Almighty, in the Name of Jesus + Christ, his Son, our Lord, and by the power of the Holy + Ghost, that thou become water exorcised for putting to flight all the power of the enemy, and do thou avail to cast out and send hence that same enemy, with all his apostate angels: through the power of the Same our Lord Jesus Christ, who shall come to judge the quick and the dead, and the world by fire. Amen.
Let us pray. (Blessing of the water) O God, Who for the salvation of mankind hast ordained that the substance of water should be used in one of thy chiefest Sacraments: favourably regard us who call upon thee, and pour the power of thy bene+diction upon this element, made ready by careful cleansing; that this thy creature, meet for thy mysteries, may receive the effect of divine grace, and so cast out devils, and put sickness to flight, that whosoever in the dwellings of thy faithful people shall be sprinkled with this water, may be made free from all uncleanness and delivered from all manner of hurt; there let no spirit of pestilence abide, nor any corrupting air: thence let all the wiles of the hidden enemy depart; and if there be aught that layeth snares against the peace or safety of them that dwell in the house, let it fly before the sprinkling of this water, so that the health which they seek through calling upon thy holy Name may be protected against all things that threaten it. Through Jesus Christ our Lord. Amen.
Blessings to You All,
