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 adored, 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. (Roman Missal)
Priests: Please catechise and inform your parishioners beforehand if you are going to use the Second Form.
