The Litmus Tests to which I so often refer on this blog, are a mixture of old and new - they are continually being added-to.
I first conceptualized them in 2020 in reference to the Birdemic and Peck, which were added onto much longer established Totalitarian Establishment strategies - such as pacifism, socialism, feminism and sexual revolution, antiracism, climate change etc.
Since 2020 there have been further Litmus Tests, such as (especially in the UK) the war against the Fire Nation. And currently there is a Litmus Test with reference to taking sides in the civil war that is splitting the globalist materialists of the Totalitarian Establishment.
(Or apparently so - because the civil war may ultimately, at the highest level, be a faked show put-on to manipulate the masses.)
It is pretty clear that the Litmus Tests never stop. As commenter Laeth has said; each new Test probes for different vulnerabilities among those people (and institutions) who had been able to hold-out against being assimilated into active support to the Totalitarian Agenda*.
Thus the healthism of the Birdemic/ Peck led to the corruption of most of the the holdouts among mainstream Christian churches... Conservative Catholics, Evangelicals and Mormons that had resisted the sexual revolution; became wildly-enthusiastic about closing their churches and suspending activities until further notice; and imposing lockdown, atomistic social isolation, and habits of systematic interpersonal fear.
Later; some of those who had successfully resisted the Birdemic manipulations, then joined with a nationally-orchestrated, media-constructed, Orwellian "two-minute hate session" against the Fire Nation - a two-minutes that has continued for three years, so far (and which is still actively attempting to create a self-annihilating all-out state of war, with the UK as prime target).
The current situation wit hte new President in the USA is but the most recent Litmus Test. This has, like previous tests, been able to subvert and "turn" a significant proportion of those "holdouts" who had resisted the Birdemic and Fire Nation Tests. It seems that perhaps a majority of "based" online anti-woke, self-identified Christians; have gone all-in for an almost delirious combination of schadenfreude with this-worldly-optimism; the whole thing focused on various Antichrist-figures among the mainstream, totalitarian establishment.
In one sense these Litmus Tests can be understood as an almost inevitable consequence of the increasing power of Satan and his demons and human servants within this-world - clearly, they will continue to win more-and-more souls to an more-certain (self-chosen) damnation.
On the other hand they may perhaps be seen as tests allowed by God; because of the opportunities each one brings for a different kind of spiritual learning, and therefore spiritual development - an education in preparation for our post-mortal resurrected life.
(Which education is, IMO, the purpose of our sustained mortal life. We each continue to live because we have more that it would be good - and perhaps essential - for us to learn.)
However, I personally do not see the Litmus test as allowed by God nor as a divinely ordained method of spiritual education. Instead I see them as things that God cannot prevent, in this world as it actually is.
My understanding is: The Litmus Tests originate variously, but become strategies due to their potential for evil and are sustained for that reason.
They are not of-God; but God can and does (as always) make the best of the bad situations that result, because of his love for each of us, as His divine children.
And we should take the same attitude of making the best spiritual use of the situations. We should regard the Litmus Tests as direct challenges - not to our peace/ prosperity/ comfort/ convenience; but challenges to our innermost spiritual freedom, the primacy of Christian love, and the requirement for absolute personal responsibility.
The core part of this is realizing that, for all their geopolitical qualities, the Litmus Tests are Not primarily about material circumstances for large numbers of people in this-world - on the contrary; their true primary reality is directed at the free individual human soul; who always-can and needs-to discern reality in-and-for-himself; whatever the pressures and distractions of this material and social world.
*Note: As I have previously said; the special significance of Litmus Tests, as with all temptations to sin, is that failure on even a single Test can be sufficient to induce a person to choose reject salvation and choose damnation. Therefore, it is a misunderstanding to express satisfaction that some particular person or institution has passed one, or several, or a majority of the Litmus Tests. In principle and in practice; even when just a single Litmus Test is failed, then that may be a sufficient basis for corruption and inversion of values. And this is made much more likely because the Global Totalitarian Establishment will reward and amplify any such failure; to convert passive acquiesce into active support.
