In Christianity, the theme of a new coming of the Cosmic Christ weaves like a thread throughout its whole history. This theme is linked with the most cherished hopes, expectations and dreams of the reappearance of Christ and of humankind's return to the Kingdom of God:

Listen!' says Jesus. 'I am coming soon!

I will bring my rewards with me, to give to each one according to what he has done. I am the first and the last, the beginning and the end'.

(Revelation 22: 12-13)

In the days after that time of trouble the sun will grow dark, the moon will no longer shine, the stars will fall from heaven, and the powers in space will be driven from their courses. Then the Son of Man will appear, coming in the clouds with great power and glory. He will send the angels out to the four corners of the earth to gather God's chosen people from one end of the world to the other. 

(Mark 13: 24-27)

Profound cosmogonic meaning is contained in these apocalyptic visions. The Son of Man appearing in the clouds symbolises the mystery of the Holy Trinity which manifests the absolute Truth of Creation. The Son of Man is Christ, the Solar Logos, the active, personified principle of God who acts as the sole Subject in the Universe; 'the clouds' are the substance of the Holy Spirit, the receptive, feminine, objective principle of God which shapes primordial matter. The phenomenon of the sun growing dark, the moon no longer shining and the stars falling from heaven symbolises the transcendence from the physical universe of human consciousness and the grasp of the new spiritual metaphysics of Creation which shines with dazzling light. This appearance of Christ will eventually come after many tribulations which are aimed at awakening us to the ultimate Truth. (See the seven horrors in 'The Trumpets' ‑ Revelation 8: 6‑13, 9: 1‑19, and 'The Bowls of God's Anger' ‑ Revelation 16: 1‑12)

God's 'chosen people' from the four corners of the Earth are all those who will be able to comprehend the Truth of God and live in accordance with it. For these people God Himself and the Cosmic Christ will shine brighter than the midday sun: 'The city has no need of the sun or the moon to shine on it, because the glory of God shines on it, and the Lamb is its lamp.' (Revelation  21: 23)

Thus, the Second Coming of Christ is the illumination of human consciousness about the Divine essence of the Universe and signals our return to the reality of the Kingdom of God. In His Second Coming Christ will appear as the transcendental Divine Truth, the glorious and victorious Christ who comes back and takes us to Himself, so that we will be where He is (John 14: 3).

In his book The Second Coming, in the chapter consecrated to the Second Coming of Christ and the reappearance of St. John, Leon Moscona reveals many aspects of the coming new Gospel of the Cosmic Christ. 

It is really staggering to contemplate the new integral mythology of the first and second coming of Christ combining the mystery of the Cross of Crucifixion with the mystery of the Cross of Immortality, the blossoming of the Rose of the Heart with the blossoming of the Rose of the World, the initiation of the True Vine with the initiation of the Universal Tree, the secrets of the Immanent Christ with the secrets of the Transcendent Christ, the Sacraments of the Earthly Church with the Sacraments of the Heavenly Church.

When the people understand these mysteries they will identify themselves as 'God's chosen people' gathered to meet the Second Coming of Christ and to witness the re-creation of the world. There are no words to express the joy and ecstasy of our spirits contemplating this Divine Mystery.
