- One and the same priest celebrant must always exercise the presidential office in all of its parts, except for those parts which are proper to a Mass at which the Bishop is present (cf. above, no. 92).
- When the Church’s needs require it, however, if sacred ministers are lacking, lay members of Christ’s faithful may supply for certain liturgical offices according to the norm of law.249 Such faithful are called and appointed to carry out certain functions, whether of greater or lesser weight, sustained by the Lord’s grace. Many of the lay Christian faithful have already contributed eagerly to this service and still do so, especially in missionary areas where the Church is still of small dimensions or is experiencing conditions of persecution,250 but also in areas affected by a shortage of Priests and Deacons.
- **Only out of true necessity ** is there to be recourse to the assistance of extraordinary ministers in the celebration of the Liturgy. Such recourse is not intended for the sake of a fuller participation of the laity but rather, by its very nature, is supplementary and provisional.252
