"The redemptive sacrifice of Christ is unique, accomplished once for all; yet it is made present in the Eucharistic sacrifice of the Church. The same is true of the one priesthood of Christ; it is made present through the ministerial priesthood without diminishing the uniqueness of Christ's priesthood: "Only Christ is the true priest, the others being only his ministers" (CCC 1545).
CONSECRATED LIFE
"Christ proposes the evangelical counsels, in their great variety, to every disciple. The perfection of charity, to which all the faithful are called, entails for those who freely follow the call to consecrated life the obligation of practicing chastity in celibacy for the sake of the Kingdom, poverty and obedience. It is the profession of these counsels, within a permanent state of life recognized by the Church, that characterizes the life consecrated to God" (CCC 915).
MARRIAGE
"Sacred Scripture begins with the creation of man and woman in the image and likeness of God and concludes with a vision of "the wedding-feast of the Lamb." Scripture speaks throughout of marriage and its "mystery," its institution and the meaning God has given it, its origin and its end, its various realizations throughout the history of salvation, the difficulties arising from sin and its renewal "in the Lord" in the New Covenant of Christ and the Church" (CCC 1602).
