The Year for Priests proposes for our reflection the figure of the priest and, in a special way, his dignity of ordained minister who celebrates the sacraments, for the benefit of the whole Church, in the Person of Christ, high and eternal priest
Priests "exercise their sacred function especially in the Eucharistic worship or the celebration of the Mass by which acting in the person of Christ ["in persona Christi"] and proclaiming his mystery they unite the prayers of the faithful with the sacrifice of their Head and renew and apply in the sacrifice of the Mass until the coming of the Lord the only sacrifice of the New Testament namely that of Christ offering Himself once for all a spotless Victim to the Father." Vatican Council II, "Lumen Gentium," No. 28: AAS 57 (1965), p. 34. Cf. also "Presbyterorum Ordinis," Nos. 2; 12; 13.
