15 In exercising their office of sanctifying, bishops should be mindful that they have been taken from among men and appointed their representative before God in order to offer gifts and sacrifices for sins. Bishops enjoy the fullness of the sacrament of orders and both presbyters and deacons are dependent upon them in the exercise of their authority. For the presbyters are the prudent fellow workers of the episcopal order and are themselves consecrated as true priests of the New Testament, just as deacons are ordained for the ministry and serve the people of God in communion with the bishop and his presbytery. Therefore bishops are the principal dispensers of the mysteries of God, as well as being the governors, promoters, and guardians of the entire liturgical life in the church committed to them. They should, therefore, constantly exert themselves to have the faithful know and live the paschal mystery more deeply through the Eucharist and thus become a firmly-knit body in the unity of the charity of Christ. "Intent upon prayer and the ministry of the word" (Acts 6:4), they should devote their labor to this end that all those committed to their care may be of one mind in prayer and through the reception of the sacraments may grow in grace and be faithful witnesses to the Lord. As those who lead others to perfection, bishops should be diligent in fostering holiness among their clerics, religious, and laity according to the special vocation of each. They should also be mindful of their obligation to give an example of holiness in charity, humility, and simplicity of life. Let them so hallow the churches entrusted to them that the feeling of the universal Church of Christ may shine forth fully in them. For that reason they should foster priestly and religious vocations as much as possible, and should take a special interest in missionary vocations.
