As well as equality being a Bad Thing to aim-at; indeed, equality is not even a real thing.
The word and concept of equality is, of course, very vague in terms of its actual (i.e. rhetorical) usage, which resembles an hypothetical black box, more than a useful category; but 'equality' can usually validly be reduced to an assertion of sameness...
Either an assertion that some-particular-things are, or ought to be, The Same.
But are things ever the same?
Well, in some sciences, especially the physical science, science there has been an assumption of sameness among things like particular chemicals or atomic particles. Yet even here, the progress of science has usually been towards finding differences among things that were originally assumed to be the same: for instance all atoms were originally assumed to be identical - even between different elements and substances. And in biology, an assumption of sameness is much less frequent, and soon breaks-down, the closer we look.
Perhaps the only genuine sameness is in mathematics (and formal logic), where the sameness is axiomatic and wholly abstract: a matter of definition.
But mathematics is not the real world.
What about in religion? Well, so far as I know, there has never been any actual, viable religion where all people are judged to be the same.
In the past, human differences were often simplified (for practical purposes) into categories, or classes of Men - but even there, there was always provision for making distinctions.
e.g. Priests may have been in a different category than non-priests; but priests were internally differentiated in many way - even down to the individual level.
But what of a divine level? Again, it seems there has never been equality of divine regard of Men - but sometimes this has been simplified into categorical levels of classes of divine esteem; which often reflected social organization.
So where does the idea of equality come into religion? Well, sometimes there is an equality of 'destination' in terms of post-mortal, afterlife fate. In some religions it seems that all Men will (sooner or later) end-up in the same situation.
For instance, the Ancient Greeks and Hebrews seem to have regarded the afterlife of all Men as a an underworld of demented ghosts: Hades/ Sheol.
Or the Eastern Religions Hinduism and Buddhism have sometimes envisaged all Men as sharing the same fate of eventually (after varying numbers of incarnations) being re-absorbed back into the divine, from which they came - at least, that goal was the same for all Men.
Christianity has always divided the destinations between at least two (not-equal) possibilities: Heaven and Hell; and this has sometimes been elaborated by additional possibilities such as Limbo and Purgatory; and by differentiation of fates and roles within both Heaven and Hell (e.g. the circles of Hell, or the layered Mormon 'Heavens') - sometimes differentiation by categories of people, sometimes at the individual level.
The main assertion of, and emphasis upon, 'equality' in Christianity is almost-wholly modern (coming after the emergence of political leftism, with is promiscuous talk of actual or aspirational 'equality'), and is related to God's supposed attitude of Love to all Men being absolutely 'equal'.
But God's 'equal' love can only be entertained as a possibility either if Love is regarded in an extremely abstract way (because in real life, including in the Bible itself, love is always differentiated and selective) -- and/or if equality is redefined into a very vague notion that because God Loves all His children, this 'must' (or should) mean that God (somehow, for some reason) loves all his children in exactly the same way and to exactly the same degree...
This supposed 'equality' has been spun into highly abstract assertions of God's absolute and unconditional - therefore equal - Love; rather as if God's love was an evenly-distributed gas, or a radiation of completely equal intensity that bathed all Men without distinction.
To my mind, this (frequent) attempt to express God's Love as equal and unconditional is probably an alien import to Christianity; either derived from politics; or apparently derived by back-projection from the (not Christian - but nonetheless held by some self-identified Christians) idea of post-mortal Men all returning to be assimilated-into the divine...
Maybe the argument hinges on the idea that if all Men end-up equally, then this happens because God regards all Men as the same.
At any rate, these two ideas of the supposedly unconditional and universally-equal Love of God, and a Nirvana-like life after death destination of all Men - seem to go-together.
For a Fourth Gospel derived and focused Christianity; I would regard it as obviously wrong to regard equality in Christianity as a Good Thing.
Christians ought instead to be trying to understand God's plans for men in the most differentiated and individualistic way possible; much as the ideal attitude of earthly human parents to their children is one that recognizes each child as individual, unique; and needing (ideally) to be regarded as such in terms of their destined and best path through mortal life and beyond.
Ideal earthly parents would not love all their children 'equally'. Neither would they love their children in a rank-order. Instead they would 1.) love all their children, and 2.) love and value each child in a particular and unique way to correspond with his or her individuality.
In other words, it is high time Christians set-aside 'equality-talk'; and began to recognize that the traditional categories and classes of past-Christianity were an imperfect representation of what is actually - from God's point of view - an individual-level scheme of Man's salvation and theosis.
