The introduction to the Ordination of a Priest has five sections. The first two are virtually identical to the prescriptions for a diaconate ordination:
1. The ordination of a priest should take place on a Sunday or holy day, when a large number of the faithful can attend, unless pastoral reasons suggest another day.
2. The ordination should take place ordinarily at the cathedra or bishop’s chair; or, to enable the faithful to participate more fully, a chair for the bishop may be placed before the altar or elsewhere. A seat for the one to be ordained should be placed so that the faithful may have a complete view of the liturgical rites.
The newly ordained has a role in the Mass:
3. The priest concelebrates with the bishop in his ordination Mass. It is most appropriate for the bishop to admit other priests to the concelebration; in this case and on this day the newly ordained priest takes the first place ahead of the others who concelebrate.
Some instructions for the sacristan or master of ceremonies:
4. The one to be ordained wears an alb (with an amice and cincture unless other provisions are made) and a deacon’s stole. In addition to what is needed for the concelebration of Mass, there should be ready: (a) the Roman Pontifical; (b) stoles for the priests who lay hands upon the candidate; (c) a chasuble for the candidate; (d) a linen gremial; (e) holy chrism; (f) whatever is needed for the washing of hands.
… and the opening procession:
5. When everything is ready, the procession moves through the church to the altar in the usual way. A deacon carries the Book of the Gospels; he is followed by the candidate then the concelebrating priests, and finally the bishop between two deacons.
