This article includes the continuation of the dedication ceremony as found in the Pontifical of 1595, and the revision of this part made in 1961. The earlier sections can be read here and here.
When the bishop has come to the faldstool, he intones the hymn Veni, Creator Spiritus, which is then sung by the choir. Meanwhile, one of the servers sprinkles ashes on the floor of the church in the form of a cross, making two lines roughly a hand-span in width, from corner to corner, crossing in the middle. (If the church is very large, the lines can be can be made in separate sections for each letter of the two alphabets, Greek and Latin.)
The bishop then kneels at the faldstool, and the choir sings the Litany of the Saints; the names of the Saint to whom the church is dedicated and those whose relics are to be placed in the altar are added to it, and each sung twice. After the invocation “That Thou may deign to grant eternal rest to all the faithful departed,” the bishop rises, and takes his crook in hand; he then sings the invocations “That Thou may deign to visit this place,” and “That Thou may deign to assign therein the guarding of the Angels;” to both the choir answers “We ask Thee, hear us.”
The bishop then adds “That Thou may deign to + bless this church and altar that shall be consecrated to Thy honor, and the name of Saint N.” The choir answers as before. He adds, “That Thou may deign to + bless and sancti + fy this church and altar that shall be consecrated to Thy honor, and the name of Saint N.”, and again, “That Thou may deign to + bless, sancti + fy and conse + crate this church and altar that shall be consecrated to Thy honor, and the name of Saint N.” Each time he makes the sign of the Cross over the church and altar with his right hand, at the places marked in red; the choir answers “We ask Thee, hear us” each time, and then finishes the Litany.
When the Litany is ended, the bishop rises, and facing the main altar, says, “Oremus”, the deacon “Flectamus genua”, and the subdeacon “Levate”, after which the bishop sings the following two prayers.
When the Litany is ended, the bishop rises and says “Let us pray.” The deacon and subdeacon do not say “Flectamus genua” and “Levate”; the bishop then says only the second of the two prayers noted above, “Be Thou magnified.” (It should be noted that as in the Missal, the prayers of the Pontifical are almost always preceded by either “Dominus vobiscum” or “Oremus. Flectamus genua. Levate.”, and “Oremus” by itself is very unusual.)
The bishop then kneels at the faldstool, and the choir sings the Litany of the Saints; the names of the Saint to whom the church is dedicated and those whose relics are to be placed in the altar are added to it, and each sung twice. After the invocation “That Thou may deign to grant eternal rest to all the faithful departed,” the bishop rises, and takes his crook in hand; he then sings the invocations “That Thou may deign to visit this place,” and “That Thou may deign to assign therein the guarding of the Angels;” to both the choir answers “We ask Thee, hear us.”

When the Litany is ended, the bishop rises, and facing the main altar, says, “Oremus”, the deacon “Flectamus genua”, and the subdeacon “Levate”, after which the bishop sings the following two prayers.
May Thy mercy go before us, we beseech Thee, o Lord, and by the intercession of all Thy Saints, may Thy clement indulgence come before our voices. Through Christ our Lord. R. Amen.The schola now sings the following antiphon, from second Vespers of the Dedication of a Church, with the canticle Benedictus, repeating it after each verse:
Let us pray. Be Thou magnified, o Lord, our God, in Thy Saints, and appear in this temple built unto Thee, so that Thou who workest all things in the children of adoption, may always be praised in Thy inheritance. Through Christ our Lord. R. Amen.
O how fearful is this place; truly this is no other than the house of God, and the gate of Heaven!While they are singing, the bishop writes the letters of the Greek alphabet in the ashes with his crook, starting from the left of the door and going to the back of the church on the right, and then Latin alphabet on the other line, starting from the right of the door and going to the back of the church on the left.
In the 1961 revision, the Veni, Creator Spiritus is suppressed. The Litany of the Saints begins as soon as the bishop comes and kneels at the faldstool; it is shortened by the removal of twenty Saints, and the removal of fourteen invocations in the second part. The name of the Saint to whom the church is dedicated and those whose relics are to be placed in the altar are added to it; the former is now sung three times, rather than twice, but the latter are sung only once. The additions to the Litany sung by the bishop himself are unaltered, and it concludes as usual.
The sprinkling of the ashes on the floor of the church and the writing of two alphabets is moved from its traditional place before the making of the Gregorian water and the aspersion of the internal walls, to after. (For the sake of convenience, I shall describe how it is done here.) Where the previous rubric said that ash was to be used, the 1961 rubric says “ash or sand”. It is no longer spread out in such a way that it fills the church in two lines from corner to corner; rather, it is laid down “before the gates of the sanctuary, or, if the multitude of the faithful assisting at the sacred action may permit that this be done, in the middle of the church, … each (line) about three meters long (i.e. just under ten feet), and about twenty centimeters wide. (i.e. just about 7 inches)” As the bishop writes the alphabet, the choir sings the antiphon “O how fearful is this place”, but with psalm 47 Magnus Dominus, rather than with the Benedictus. No mention is made of repeating the antiphon.
