Some are of opinion that heaven is everywhere, as God is everywhere. According to this view, the blessed can move about freely in every part of the universe, and still remain with God and see everywhere. Everywhere, too, they remain with Christ (in His sacred Humanity) and with the saints and the angels. For according to the advocates of this opinion, the spatial chasms of this world can no longer impede the perception of those blessed.
In general, however, theologians deem more appropriate that there should be a special and glorious abode, in which the blessed have their peculiar home and where they usually abide, even though they be free to go about in this world. For the surroundings in the midst of which the blessed have their dwelling must be in accordance with their happy state; and the internal union of charity which joins them in affection must find its outward expression in community of habitation. At the end of the world, the earth together with the celestial bodies will be gloriously transformed into a part of the dwelling-place of the blessed.[1] Hence, there seems to be no sufficient reason for attributing a metaphorical sense to those numerous utterances of the Bible, which suggest a definite dwelling-place of the blessed. Theologians, therefore, generally hold that the heaven of the blessed is a special place with definite limits. Naturally, this place is held to exist, not within the earth, but in accordance with the expressions of Scripture, without and beyond its limits. All further details regarding its locality are quite uncertain. The Church has decided nothing on this subject.
