Continuing through the Catechism of the Catholic Church as it relates to prophecy:
731 On the day of Pentecost when the seven weeks of Easter had come to an end, Christ’s Passover is fulfilled in the outpouring of the Holy Spirit, manifested, given, and communicated as a divine person: of his fullness, Christ, the Lord, pours out the Spirit in abundance.
732 On that day, the Holy Trinity is fully revealed. Since that day, the Kingdom announced by Christ has been open to those who believe in him: in the humility of the flesh and in faith, they already share in the communion of the Holy Trinity. By his coming, which never ceases, the Holy Spirit causes the world to enter into the “last days,” the time of the Church, the Kingdom already inherited though not yet consummated.
We have seen the true Light, we have received the heavenly Spirit, we have found the true faith: we adore the indivisible Trinity, who has saved us.
If there is something that should be smack-you-in-the-head obvious, it’s that the Kingdom of God has been with us since The Resurrection, and that the “end-times” is all about the growth of the Kingdom with the Trinity fully revealed to us (at least in definition and understanding of the nature of God as 3 Persons in one God. It is still ultimately a mystery of faith that 3 Persons are of the same substance.)
This is vitally important to recall as Biblical prophecy is studied. Too often, we imagine the Kingdom as a futuristic experience. We can take biblical references as such to mean that it is still something we are waiting for. But it is in the present. It is true that the perfected Kingdom, absent all evil, is a futuristic hope and promise, but the Kingdom itself has been established.
Just like physical kingdoms that existed and had enemies and fought physical wars in defense of the kingdom, today’s Kingdom is a spiritually manifest one, and the wars are in that plane as well. The presence of evil and the fight waged by Satan is not evidence of a kingdom that is losing the battle, nor is it evidence that the Kingdom has yet to arrive. In fact, the more vociferously this war is waged by the enemy, the more indicative it is that the Kingdom at hand is worthy – in the enemy’s eyes – of defeat. A house divided against itself cannot stand – so why focus so much energy on destroying a church that is a falsehood? It would make no sense to do so.
