In every age there have been men and women who, obedient to the Father’s call and to the prompting of the Spirit, have chosen this special way of following Christ, in order to devote themselves to him with an “undivided” heart (cf. 1 Cor 7:34). Like the Apostles, they too have left everything behind in order to be with Christ and to put themselves, as he did, at the service of God and their brothers and sisters. In this way, through the many charisms of spiritual and apostolic life bestowed on them by the Holy Spirit, they have helped to make the mystery and mission of the Church shine forth, and in doing so have contributed to the renewal of society.
