The Church that Jesus Christ founded on Peter as it’s rock was from the beginning a hierarchical Church because of the ministry of the word and sacrament (“Holy Orders”) committed to the Apostles. In the words of Saint Tertullian: The Church from the Apostles, the apostles from Christ, and Christ from God. But the Church is likewise established as a sacrament of salvation in that it comes to us from God in Christ. Intimately united with Christ as Head, the Church is an organic body that shares in the various functions of Christ as Priest, Prophet, and King. Hence, all the people of God constitute a priestly people. However; to the apostles was given a ministry that differed specifically from the ministry of the priesthood of the laity, and particularly as regards to the prophetic ministry of the word, the priestly ministry of the sacraments, and the kingly or pastoral ministry of government of churches. to provide for the continuation of these various ministries, the apostles designated certain men to be pastors of the flock. The ministerial priest is therefore configured to Christ through the gift of the Holy Spirit and the character recieved at ordination, which is given through the Church and administered by the bishop. The priesthood received (“IS”) the priesthood of Christ, as is the power that is meant to be used for the service of the people. The priest is therefore a man for others and is ordained for ministry. But the ministry is exercised to the whole Church, to build up the body of Christ and extend his kingdom. The priesthood is eminently a spiritual ministry and even when it touches the temporal or secular order; it is always in view of every man, woman, and child’s sanctification and salvation, as was the ministry of Christ and the apostles. Like all Christians, bishops, and priests are obliged by their baptismal commitment to strive for the perfection of charity and configuration to Christ. However; a priest commitment is a special obligation by reason of their priestly ordination and their pastoral ministry. The priest is identified with a holy mission and he should sanctify himself by the very works of his ministry, but prior to that, in his very person, he has been sealed by the Holy Spirit and configured to Christ as (“alter Christus”). Therefore; in speaking of the priest’s important call to perfection. Vatican Council II states that there is a relationship between the holiness of the priest and the fruitfulness of his ministry and ("God ordinarily prefers to show his wonders through those men who are submissive to the impulse and guidance of the Holy Spirit and who, because of their intimate union with Christ and their holiness of life, are able to say with Saint Paul: “It is no longer I who live, but Christ who lives in me”). Gal. 2:20
