"All Christians in any state or walk of life are called to the fullness of Christian life and to the perfection of charity." All are called to holiness: "Be perfect, as your heavenly Father is perfect."
In order to reach this perfection the faithful should use the strength dealt out to them by Christ's gift, so that . . . Doing the will of the Father in everything, they may wholeheartedly devote themselves to the glory of God and to the service of their neighbor. Thus the holiness of the People of God will grow in fruitful abundance, as is clearly shown in the history of the Church through the lives of so many saints.
