If man wishes to build for himself a world conception, he rightly strives toward harmonizing the individual parts...
One who approaches the world with the expectation that everything must explain itself without contradiction, as if it arose from an undivided foundation of the world, will experience many disappointments when he faces the world and its experiences in an unprejudiced way. It is traditional for the human being to treat all that he perceives in the world according to a pastoral world conception, in which everything is led back to the undivided, divine, primordial foundation; everything stems from God and therefore must be understandable as a unity.
This is not the case now, however. What surrounds us in the world as experience does not stem from the undivided primordial foundation. Rather it stems from spiritual individualities different from one another. Different individualities work together in all that surrounds us in the world as experience. This is how it is above all...
Various individualities work together in influencing these events that are relatively independent of each other. If you do not take this into consideration, if you assume everywhere an undivided foundation of the world, you will never understand these events. Only when you take into consideration what is to a certain degree the ebb and flow of events, the varied individualities who work with or against one another, only then will you understand these things in the right way.
This matter is indeed connected with the deepest mysteries of human evolution. Only the monotheistic feeling has veiled this fact for centuries or millennia, but one must consider it.
If one wishes to progress today, therefore, with questions of a world conception, above all one must not confuse logic with an abstract lack of contradiction. An abstract lack of contradiction cannot exist in a world in which individualities are working together independently of one another.
A striving for conformity will therefore always lead to an impoverishment of concepts; the concepts will no longer be able to encompass the full reality. Only when these concepts are able to take hold of this world full of contradictions, which is the true reality, will they be able to encompass the full reality.
From Individual Spirit Beings and the Undivided Foundation of the World: Part 2 by Rudolf Steiner.
This particular section of a lecture by Rodolf Steiner jumped out at me; because he shares my own understanding that monotheism is an understandable but misguided urge; one that can only be achieved by an 'impoverishment of concepts', an ignoring of primary and intuitively-known realities, that - in the end, and especially at present - plays into sustaining this age of secular materialism.
In other words, a highly abstract monotheism, one that primarily asserts the unity of the world, is hostile to our intuitive knowledge of the multiplicity of agent Beings in reality. This world is Not merely 'aspects' of a primordial unity; it is a Society of Beings.
And this is why, for Christians, Love is the primary necessity; because it is Love which harmonises, and aligns the purposes of Beings into a participation in creation - Beings whose wills otherwise would be chaotically at war.
Christians are One in Love and Purpose - not in monotheistic Being.
There is a qualitative distinction between the false monotheistic harmony of unity, and the true Christian harmony of Love.
This is why it is important for Christians to acknowledge that in deepest truth they are not monotheists, nor are they 'Trinitarian' monotheists - but that Christianity implicitly acknowledges and works-with the genuine autonomy of many, many Beings.
