In the past Christianity - or more exactly 'being a Christian' - has often become extremely complex.
Often so complex that ordinary people could not get it all and had to rely on experts (pastors, priests, theologians etc.).
Often, indeed, so complex that no single person could learn it, nor hold it all in mind; and it required long documentation, professional education, and sub-committees of specialized experts who subdivided the subject into manageable chunks.
Yet, there are places in the New Testament where it seems clear that someone could become a Christian in an moment, on the basis of extremely little and very simple information as to what this entailed.
Of course; from that point - being a Christian might then mean submitting to some authoritative expert or group with respect to living in terms of a complex lifestyle and set of observances.
Or perhaps not always - it isn't absolutely clear. Maybe it was originally intended that 'following Jesus' was cognitively very simple indeed; and the guidance of the Holy Ghost was not meant to be captured in scores/ hundred/ thousands of doctrines, laws, practices, mandatory and exclusional practices...
However it then was; I find myself increasingly convinced that Christianity Now, in 2023, is meant to be simple - not complex; because then it can be followed by discernment, with clarity and assurance, by individuals - each of whom has taken final-responsibility for his own salvation and spiritual development.
Christianity is about binary (hence simple) choices; in a world where the mainstream secular world pretends that things are so complex that only (officially-accredited) experts can inform us what is good, true and beautiful - and what (therefore) we ought to do.
On the other side; the mainstream-approved spirituality of oneness asserts that the highest wisdom is to see through duality and recognize that ultimately every-thing is one-thing; and nothing really matters except to go beyond the illusion of duality. In different word: we ought to stop discerning...
Stop all discerning except to reject all distinctions and divisions - including good v evil, truth v lies, beauty v ugliness, and coherence v incoherence).
(i.e. The single allowable discernment is that all is one; and anything else is wrong, spiritually harmful, and should be shunned.)
It seems everybody important and influential is agreed that duality and binary choices are wrong; either because they are too-simple, or not-simple-enough.
But my understanding is that Christianity and Christian life boils-down to exactly such prohibited simple, binary choices; and that is how we ought to know the world.
We should see the whole of this inconceivably complicated world as a spiritual war between two sides, between which we can and must choose - and this choice is made possible to every individual person, in every relevant circumstance (relevant to the fate of our own soul) by understanding the matter in the correct way; which is simple and dichotomous.
Complexity and oneness are thus equally the enemy of Christian discernment.
