Pope Francis has asked the Catholic Church to devote the 2015 Liturgical Year as the Year of Consecrated Life. What does that mean, you ask? Canon Law states:
The life consecrated through the profession of the evangelical counsels is a stable form of living by which the faithful, following Christ more closely under the action of the Holy Spirit, are totally dedicated to God who is loved most of all, so that, having been dedicated by a new and special title to His honor, to the building up of the Church, and to the salvation of the world, they strive for the perfection of charity in the service of the kingdom of God and, having been made an outstanding sign in the Church, foretell the heavenly glory.

So, it is a form of Christian living by those faithful who feel called to follow Jesus Christ in a more exacting way recognized by the Church, like priests, sisters, and brothers.
