YOUCAT Question n. 250 - Part V. How does the Church understand the sacrament of Holy Orders?

(Youcat answer - repeated) The priests of the Old Covenant saw their duty as mediating between heavenly and earthly things, between God and his people. Since Christ is the “one mediator between God and men” (1 Tim 2:5), he perfected and ended that priesthood. After Christ there can be an ordained priesthood only in Christ, in Christ’s sacrifice on the Cross, and through a calling and apostolic mission from Christ.

A deepening through CCC

(CCC 1547) The ministerial or hierarchical priesthood of bishops and priests, and the common priesthood of all the faithful participate, "each in its own proper way, in the one priesthood of Christ." While being "ordered one to another," they differ essentially (LG 10 § 2). In what sense? While the common priesthood of the faithful is exercised by the unfolding of baptismal grace -a life of faith, hope, and charity, a life according to the Spirit-, the ministerial priesthood is at the service of the common priesthood. It is directed at the unfolding of the baptismal grace of all Christians. The ministerial priesthood is a means by which Christ unceasingly builds up and leads his Church. For this reason it is transmitted by its own sacrament, the sacrament of Holy Orders.

Reflecting and meditating 

(Youcat comment) A Catholic priest who administers the sacraments acts not on the basis of his own power or moral perfection (which unfortunately he often lacks), but rather “in persona Christi”. Through his ordination, the transforming, healing, saving power of Christ is grafted onto him. Because a priest has nothing of his own, he is above all a servant. The distinguishing characteristic of every authentic priest, therefore, is humble astonishment at his own vocation.

(CCC Comment)

(CCC  1548 b) Now the minister, by reason of the sacerdotal consecration which he has received, is truly made like to the high priest and possesses the authority to act in the power and place of the person of Christ himself (virtute ac persona ipsius Christi) (Pius XII, encyclical, Mediator Dei: AAS, 39 (1947) 548). Christ is the source of all priesthood: the priest of the old law was a figure of Christ, and the priest of the new law acts in the person of Christ (St. Thomas Aquinas, STh III, 22, 4c).
