During the Hallelujahs, as the Gospel Book or Bible is carried (or in the case of a High Feast, the Gospel Procession is forming), the celebrant (or deacon) moves directly to the altar, genuflects, and takes the missal stand, with the Altar Book on it, in both hands to move it to the Gospel side, so that it directly mirrors its former place on the Epistle side. While moving it, he bows briefly at the center. Then, bowing again as he leaves the altar, he approaches the place of reading, whether the Gospel horn or the pulpit (or, in the case of a Gospel procession, he joins the procession down the aisle) for the reading of the Gospel (unless there is a deacon to read it, in which case the celebrant remains at the altar, facing the reader). He processes last, behind crucifer, torches, and book-bearer (assuming there is no deacon).
At St. Paul's, the congregation sings the triple Hallujah, the choir sings the verse, and the congregation repeats the triple Hallelujah. If there is a Gospel procession, the triple Hallelujah is repeated a third time, after the Gospel.
The celebrant (or deacon) does not hold the Book from which he reads, although he does turn any necessary pages.
