Already dedicated to him through Baptism, the person who surrenders himself to the God he loves above all else thereby consecrates himself more intimately to God’s service and to the good of the Church. By this state of life consecrated to God, the Church manifests Christ and shows us how the Holy Spirit acts so wonderfully in her. and so the first mission of those who profess the evangelical counsels is to live out their consecration. Moreover, “since members of institutes of consecrated life dedicate themselves through their consecration to the service of the Church they are obliged in a special manner to engage in missionary work, in accord with the character of the institute.”
In the Church, which is like the sacrament – the sign and instrument – of God’s own life, the consecrated life is seen as a special sign of the mystery of redemption. To follow and imitate Christ more nearly and to manifest more clearly his self-emptying is to be more deeply present to one’s contemporaries, in the heart of Christ. For those who are on this “narrower” path encourage their brethren by their example, and bear striking witness “that the world cannot be transfigured and offered to God without the spirit of the beatitudes.”
Whether their witness is public, as in the religious state, or less public, or even secret, Christ’s coming remains for all those consecrated both the origin and rising sun of their life:
For the People of God has here no lasting city, . . . [and this state] reveals more clearly to all believers the heavenly goods which are already present in this age, witnessing to the new and eternal life which we have acquired through the redemptive work of Christ and preluding our future resurrection and the glory of the heavenly kingdom.
