Forgive slightly updated copy-pasta from an earlier reply I did on why that specific mindset induced by that force was so dangerous:
Obviously the key issue here is spiritual slavery, and the kinds of restrictions and outright pathologies that develop when EVERYONE is a slave.
So it’s that I want to address: why do these desert cults have such toxic power compared to the types of magico-religious societies, and beliefs, of the other pantheons (Norse, Greek, Indian, Egyptian, Aztec, etc)?
Simple answer – the statement that there is only one god.
Once you have that in place, you open up a small but critical need for believers to start thought-policing themselves and others, and to start limiting spiritual exploration and experiences, because you cut out the possibility of calling on ANY other entity, which slowly becomes the ancestors, nature spirits, you also get to create social and later, religious/criminal crimes to prosecute anyone whose actual experience is that other spirits exist.
It’s like 2 people trying to hike and follow compass bearings, a teeny 2 degree difference doesn’t seem huge at first, but go 10, 20, 50 miles and you’ve diverged so far that you’re visibly on a different route.
Cut out ancestors, and you replace the sense of identity with that of the Church, its esteemed figures, and the clergy, which – well, we’ve seen how that worked out for the Catholics, and it happens elsewhere even with married clergy.
Remove the right to contact the dead at all, you have people left in dread and fear, which then means you can drive in the wedge of saying “you MUST comply with these rules about everything, or you will burn for all eternity in hellfire and damnation.”
Remove the chance to call on other spirits, suddenly there’s only one go-to god for all your needs, and of course, by this stage you’re happy to burn anyone who does magick, has different beliefs, or sees spirits.
One god means justification for imposing a pre-set belief structure with multiple limitations, ALL of which are disempowering and spiritually enslaving.
Introduce blasphemy and heresy laws, so there’s not only ONE god, but people must believe in “Him” in the exact same way and perform the exact same observances - and bam, you’ve created an immediate justification for killing people you don’t like, something that happens with the (almost always FALSE) accusations against people for dishonouring the Qu’ran in many countries right now, and which led to the deaths of millions across European history.
It also leads to the creation of the concept of thought-crimes, which were more or less unknown prior to this (people were judged on their actions, not for having incorrect beliefs), then you also get the concept found in these religions that all humans are EQUAL, which again looks nice on paper, because who wants to think someone might be better than them, right?
But then you get marxism, the next mutation, which is REALLY big in thoughtcrimes and on violence and brutal mass murder of those who dare believe a different system may be better.
So again, you take something that may, to a starving peasant, look reasonable enough, and you end up with over 100 million dead, for having the wrong type of beliefs, a concept that began with the Abrahamic faiths and the steadily tightening noose which it creates through the insistence, and this isn’t a mistranslation, that (first) only one god could be worshipped, and which later became the statement that there is only one god, period.
And of course, this one “God” smiling merrily on its faithful still creates various requirements to convert or kill those filth who fail to see The Truth™ - something that has gone on forever and been rekindled with more zeal thanks to islam, possibly the nuttiest interpretation of the "there is only one ‘God’ and you must worship him as I do” because, of course, along with jihad in infidel nations, Muslims do also like to kill different kinds of Muslims quite enthusiastically, which is why they then have to flee Muslim nations in such great numbers.
Finally, that people will act in previously unthinkably inhumane ways when they feel the have the sanction of authority was demonstrated in both the Milgram experiment, which was duplicated with similar results on several different occasions, and also the Stanford Prison experiment.
What higher authority can there be than “God” and all the writings and teachings in a society that strives to worship “Him” with the utmost devotion and fervency, in order to avoid eternal torment?
While all societies and belief systems may at times veer into this murky territory, the Abrahamic faiths which rest on having doctrines in a Book which can never be altered, and a whole invested structure to enforce compliance of thought, belief, and practice, open this up to be a normal manner of proceeding in society, instead of a temporary aberration.
This isn’t a “slippery slope” fallacy or warning of something that I fear may happen, but which seems unlikely – this is recorded human history for the last two millenia, and the present day’s main source of political tensions, and in parts of western Europe, massive social upheaval.
So, that’s my analysis of why these faiths are so abhorrent, so opposed to everything magick and ascent stands for, and so fundamentally anti-human from root to tip. 
One thing I want to add, is that I don’t rule out the possibility that the figure we call Jesus was, at first, a person or syncretised group who had taken the high level of magick and what amounted to theogensis (self-identification as not just A god, but THE god - the creative Source) to a point of excellence, which is what the PGM hint at, what can be seen underlying the Mediterranean syncretism that we find in hermetic magick (and explained in full detail in Stephen Flowers’ book of that name, spelled without the K).
So for that reason I don’t find it weird if people want to work with that figure, archetype, whatever.
But the fact his cult became one of the heaviest shackles of oppression, very rapidly, and was the tool by which first Europe and later, other cultures, were culturally genocided and stripped of their native spirituality and ancestral beliefs means I don’t personally want to dabble in it either, because sifting the murk from the entire thing when it has little relevance to my present day life, and when the gods, spirits, and teachings he would have absorbed are available to me in the same way, seems like a regressive step.
But I do grant the possibility of it, based on what I’ve read and on various other patterns that seem to repeath through history, the same way I accept that some of the saints performed miracles, but it’s my contention that they performed them within Xianity because that was literally the only game in town, and NOT because it’s unique in granting powers, especially when you consider that large numbers of Xians on the Protestant side would have been very happy to burn them at the stake, and tear down those who revere them as idolators…
