KINGDOM OF GOD (OF HEAVEN): The reign or rule of God: “the kingdom of God is . . . righteousness and peace and joy in the Holy Spirit” (Rom 14:17). The Kingdom of God draws near in the coming of the Incarnate Word; it is announced in the Gospel; it is the messianic Kingdom, present in the person of Jesus, the Messiah; it remains in our midst in the Eucharist. Christ gave to his Apostles the work of proclaiming the Kingdom, and through the Holy Spirit forms his people into a priestly kingdom, the Church, in which the Kingdom of God is mysteriously present, for she is the seed and beginning of the Kingdom on earth. In the Lord’s Prayer (“Thy Kingdom come”) we pray for its final glorious appearance, when Christ will hand over the Kingdom to his Father (541-554, 709, 763, 2816, 2819).
