After the accusation has been lawfully made, and three days have been passed in fasting and prayer, the priest, clad in his sacred vestments with the exception of his outer garment, shall take with a tongs the iron placed before the altar; and, singing the hymn of the three youths, namely, “Bless him all his works,” he shall bear it to the fire, and shall say this prayer over the place where fire is to carry out the judgment: “Bless, O Lord God, this place, that there may be for us in it sanctity, chastity, virtue and victory, and piety, humility, goodness, gentleness and plenitude of law, and obedience to God the Father and the Son and the Holy Ghost.”--After this, the iron shall be placed in the fire and shall be sprinkled with holy water; and while it is heating, he shall celebrate mass. And when the priest shall have taken the Eucharist, he shall adjure the man who is to be tried ... and shall cause him to take the communion.--Then the priest shall sprinkle holy water above the iron and shall say: “The blessing of God the Father, the Son, and the Holy Ghost descend upon this iron for the discerning of the right judgment of God.” And straightway the accused shall carry the iron to a distance of nine feet. Finally, his hand shall be covered under seal for three days, and if festering blood be found in the track of the iron, he shall be judged guilty. But if, however, he shall go forth uninjured, praise shall be rendered to God.
