Other civilizations, communities of sentient beings living on other planets in other galaxies/universes.
Yes, there is only One Universal Father-Mother, One Infinite Spirit. Following from my 2 posts on page 2, we consider again that life on other planets would be subject to their own special conditions, history, predispositions, so that they might not need a program of 'salvation' in the extact way that we have here on this planet. To assume that all other planets must undergo a plan of salvation or be subject to a theological belief-system such as formulated on this one, is an unfounded assumption.
In an evolving universe of millions of inhabited worlds, its logical to assume that each planet would vary in their evolutionary unfoldment and have different culture-conditions affecting their progress.
There are no spiritual implications that affect 'us' necessarily, if other planets follow along their own lines of spiritual development, salvation or liberation in the Father's eternal plan. This might expand us further to consider that even on our own planet, there are more ways than just one religious cult or tradition, that souls can know and experience God who is a universal power and presence. 'God' is the one divine reality that alone is absolute in this world and all worlds, - the great diversity of culture, religious tradition/mythos and methodoligies are 'relative' to the various conditionings of man's psyche and culture.
