14. After the Solemn Intercessions, the solemn Adoration of the Holy Cross takes place. Of the two forms of the showing of the cross presented here, the more appropriate one according to pastoral needs should be chosen.
The Showing of the Holy Cross
15. The Deacon accompanied by ministers, or another suitable minister, goes to the sacristy, from which, in procession, accompanied by two ministers with lighted candles, he carries the Cross, covered with a violet veil, through the church to the middle of the sanctuary.
The Priest, standing before the altar and facing the people, receives the Cross, uncovers a little of its upper part and elevates it while beginning the Ecce lignum Crucis (Behold the wood of the (cross). He is assisted in singing by the Deacon or, if need be, by the choir. All respond: come, let us adore. At the end of the singing, all kneel and for a brief moment adore in silence, while the Priest stands and holds the cross raised.
Then the priest uncovers the right arm of the cross and again, raising up the Cross, begins, Behold the wood of the Cross and everything takes place as above.
Finally, he uncovers the Cross entirely and, raising it up, he begins the invitation Behold the wood of the Cross a third time and everything takes place like the first time.
16. The Priest or the Deacon accompanied by ministers, or another suitable minister, goes to the door of the church, where he receives the unveiled Cross and the ministers take lighted candles; them the procession sets off through the church to the sanctuary. Near the door, in the middle of the church, and before the entrance of the sanctuary , the one who carries the Cross elevates it, singing Behold the wood of the Cross, to which all respond Come, let us adore. After each response all kneel and for a brief moment adore in silence, as above.
THE ADORATION OF THE HOLY CROSS
17. Then, accompanied by two ministers with lighted candles, the Priest or the Deacon carries the Cross to entrance of the sanctuary or to another suitable place and there puts it down or hands it over to the ministers to hold. Candles are placed on the right and left sides of the Cross.
18. For the Adoration of the Cross, first Priest Celebrant alone approaches, with the chasuble and his shoes removed, if appropriate. Then the clergy, the lay ministers, and the faithful approach, moving as if in procession, and showing reverence to the Cross by a simple genuflection or by some other sign appropriate to the usage of the region, for example, by kissing the Cross.
19. Only one Cross should be offered for adoration. If, because of the large number of people, it is not possible for all to approach individually, the Priest, after some of the clergy and faithful have adore, takes the Cross and, standing in the middle before the altar, invites the people in a few words to adore the Holy Cross and afterwards holds the Cross elevated higher for a brief time, for the faithful to adore it in silence.
20. While the adoration of the Holy Cross is taking place, the antiphon, Crucem tuam adoramus (we adore your Cross, O Lord), the hymn Crux fidelis (faithful Cross) or other suitable chants are sung, during which all who have already adored the Cross remain seated.
