Vatican II Document on the Church
The Church, whose mystery is being set forth by this Sacred Synod, is believed to be indefectibly holy. Indeed Christ, the Son of God, who with the Father and the Spirit is praised as “uniquely holy,” loved the Church as His bride, delivering Himself up for her. He did this that He might sanctify her. He united her to Himself as His own body and brought it to perfection by the gift of the Holy Spirit for God’s glory. Therefore in the Church, everyone whether belonging to the hierarchy, or being cared for by it, is called to holiness, according to the saying of the Apostle: “For this is the will of God, your sanctification”. However, this holiness of the Church is unceasingly manifested, and must be manifested, in the fruits of grace which the Spirit produces in the faithful; it is expressed in many ways in individuals, who in their walk of life, tend toward the perfection of charity, thus causing the edification of others; in a very special way this (holiness) appears in the practice of the counsels, customarily called “evangelical.” This practice of the counsels, under the impulsion of the Holy Spirit, undertaken by many Christians, either privately or in a Church-approved condition or state of life, gives and must give in the world an outstanding witness and example of this same holiness. Thus it is evident to everyone, that all the faithful of Christ of whatever rank or status, are called to the fullness of the Christian life and to the perfection of charity; by this holiness as such a more human manner of living is promoted in this earthly society. In order that the faithful may reach this perfection, they must use their strength accordingly as they have received it, as a gift from Christ. They must follow in His footsteps and conform themselves to His image seeking the will of the Father in all things. They must devote themselves with all their being to the glory of God and the service of their neighbor. In this way, the holiness of the People of God will grow into an abundant harvest of good, as is admirably shown by the life of so many saints in Church history. Therefore, all the faithful of Christ are invited to strive for the holiness and perfection of their own proper state. Indeed they have an obligation to so strive. Let all then have care that they guide aright their own deepest sentiments of soul. Let neither the use of the things of this world nor attachment to riches, which is against the spirit of evangelical poverty, hinder them in their quest for perfect love. Let them heed the admonition of the Apostle to those who use this world; let them not come to terms with this world; for this world, as we see it, is passing away.
