The following is from Pope Benedict's remarks before the Angelus on the 25th of November A.D. 2012:
Dear brothers and sisters,
Today the Church celebrates Our Lord Jesus Christ, King of the Universe. This solemnity comes at the end of the liturgical year and brings together the mystery of Jesus “firstborn from the dead and ruler of the kings of the earth” (Collect Year B), extending our gaze towards the full realisation of the Kingdom of God, when God will be all in all (cf 1 Cor 15.28).
Saint Cyril of Jerusalem says: “We announce not only the first coming of Christ, but also a second which is much more beautiful than the first. The first, in fact, was a manifestation of suffering, the second brings the diadem of divine kingship…..in the first, He was subject to the humiliation of the Cross, in the second He is surrounded and glorified by a host of angels” (Catechesis XV,1 Illuminandorum, De secundo Christi adventu: PG 33, 869 A).
All the mission of Jesus and the contents of His message consist in announcing the Kingdom of God and implementing it among men through signs and wonders. “But – as the Second Vatican Council reminds us – above all, the Kingdom is made manifest through the person of Christ (Lumen gentium, 5), who established it through His death on the Cross and His Resurrection, whereby He showed Himself to be the Lord and Messiah, the High Priest for eternity.
This Kingdom of God was entrusted to the Church, which is the “seed” and the “beginning”, and has the task of announcing it and spreading it amongst all peoples through the strength of the Holy Spirit.
At the end of time, the Lord will deliver the Kingdom to God the Father and will present to Him all those who have lived according to the commandment of love.
[ . . . ] May the Virgin help each one of us to live this present time as we await the return of the Lord, as we decisively pray to God: “Your Kingdom come”, and as we carry out those works of light which bring us ever closer to Heaven, knowing that, in the tormented affairs of history, God continues to build His Kingdom of love.
