Thy Kingdom Come, Thy Will Be Done

From the Catechism of the Catholic Church:

1042 At the end of time, the Kingdom of God will come in its fullness. After the universal judgment, the righteous will reign for ever with Christ, glorified in body and soul. The universe itself will be renewed...

1043 Sacred Scripture calls this mysterious renewal, which will transform humanity and the world, "new heavens and a new earth."It will be the definitive realization of God's plan to bring under a single head "all things in [Christ], things in heaven and things on earth."

1045 For man, this consummation will be the final realization of the unity of the human race, which God willed from creation and of which the pilgrim Church has been "in the nature of sacrament."...The beatific vision, in which God opens himself in an inexhaustible way to the elect, will be the ever-flowing well-spring of happiness, peace, and mutual communion.

Very interesting. I'd never read that before.

From The World Order of Baha'u'llah by Shoghi Effendi:

The principle of the Oneness of Mankind - the pivot round which all the teachings of Bahá'u'lláh revolve - is no mere outburst of ignorant emotionalism or an expression of vague and pious hope....Its implications are deeper, its claims greater than any which the Prophets of old were allowed to advance...

It represents the consummation of human evolution...

[It] carries with it no more and no less than a solemn assertion that attainment to this final stage in this stupendous evolution is not only necessary but inevitable, that its realization is fast approaching, and that nothing short of a power that is born of God can succeed in establishing it.

So marvellous a conception finds its earliest manifestations in the efforts consciously exerted and the modest beginnings already achieved by the declared adherents of the Faith of Bahá’u’lláh who, conscious of the sublimity of their calling and initiated into the ennobling principles of His Administration, are forging ahead to establish His Kingdom on this earth. It has its indirect manifestations in the gradual diffusion of the spirit of world solidarity which is spontaneously arising out of the welter of a disorganized society.
