For a couple of years back in 2010-11, I was deeply immersed in Eastern Orthodox Christianity (as can be seen from this blog, at that time) - and I was especially interested by that tradition's embrace of mysticism and spiritual experience; how this 'worked' and how they dealt with the problems.
The US lay-monk Seraphim Rose (later a priest-monk) wrote on this topic with what seemed like great insight and a full acknowledgement of modern conditions.
What I derived from this; was that the ascetic monks and hermits of the EO tradition (including the millennium before the Great Schism division of the Catholic church; which was caused by divergence of the Western Latin tradition - especially the emerging influence of philosophical theology) were indeed actively seeking a direct and personal relationship with the divine and with spiritual Beings - with God, Jesus Christ, the Holy Ghost, Mary the mother of God, angels, and saints - dead and living.
This active seeking of mystical spiritual experience was pursued by very extreme measures! Including extreme asceticism (lack of food, extremes of heat or cold, immobility,) and heroic vigils (staying awake praying for many hours, sometimes is adverse conditions), and by prolonged meditation including solitude for extended periods - sometimes years.
The EO tradition is, however, very aware of the problem of achieving spiritual experiences that are demonic rather than with representatives of God.
This is often represented as demonic attack, or sometimes of succumbing to temptations such as spiritual pride, or being deceived. Some of the greatest of Saints are represented as susceptible - for example it seems that England's greatest Saint - Cuthbert - was assailed (i.e. badly tempted) by demons when he went into solitude on the island of Inner Farne, off the coast of Northumberland.
Seraphim Rose also explained that there was no valid method or system by which angels and demons could be distinguished reliably, because demons were capable of impersonating angels convincingly; and because the mystic's own evaluations were affected by his own (inevitable, because human) sinful impulses.
According to SR; over many centuries, the best method for protecting mystics from demonic temptations was a Spiritual Father who had himself known and overcome such temptations, and who might reasonably be assumed to be wholly dedicated to the spiritual good of his spiritual sons and daughters. There was (especially, and in the end, only) in Russia an unbroken lineage of Spiritual Fathers in the premier monasteries, that ensured the overall and across-time integrity of the Russian Orthodox tradition.
But this lineage was broken, permanently, with the Russian Revolution of 1917; and the subsequent murder of the Tsar and his family, and (essentially) all of the true-hearted Bishops, Abbots and holy monks - except those who escaped overseas and were dispersed in non-Orthodox nations (and they left no heirs of their stature).
What I got from this was that direct mystical spiritual-contact was essential to Eastern Orthodoxy over many, many centuries; therefore it was worth taking the risks of being deceived by demons - even though there was no really reliable method of ensuring that some aspirants were not deceived.
There could be, and was, pre-selection of those monks who were best motivated - before they were allowed to become extreme ascetics, or hermits. But this was no guarantee, since all Men are sinful, hence susceptible, to some extent.
And even the best supervision by Holy Fathers did not reach into the 'desert' conditions of the hermits, which may last for years - e.g. there was nobody to supervise St Cuthbert in the harsh solitude of Inner Farne.
But the background to all this implicitly seems to have been that personal contact between Men and spiritual Beings, and God; was so vital that risks must be taken.
Eastern Orthodoxy works in a society in which there is a communal spirituality, such that individuals are immersed in the group mind of the people; such that the Tsar really can represent his people in relation to God; and monks really can be intermediaries between the divine and the mass of lay-people.
But modern Western consciousness excludes this possibility; and therefore we are confronted by a choice between - on the one hand - personally taking the same kind of risks that the Eastern Orthodox monks used to take - but without the possibility of valid human supervision (because the churches are all net-corrupted, and Men of the spiritual stature of past Holy Fathers are not to be found - Seraphim Rose was very definite about that).
And - on the other hand - practicing a second-hand faith.
Practicing, that is, a Christianity that has lost its beating heart of contact with the divine, angels, and good-spirits of other kinds; a Christianity of mere scholarship... A Christian faith that is about being a Christian - got from books and other-people, following rules and rituals, doing set tasks, and expressing certain formulae of words - rather than actually being a Christian.
That mainstream modern Christianity is merely second-hand and not a real faith and therefore weak and easily (eagerly!) corruptible, was made obvious in 2020 - if it was not already so.
The problem is that being a second-hand Christian, is another way of Not being a Christian.
That is why a second-hand Christianity that engages in spiritual scaremongering, and eschews or proscribes direct and personal spiritual contacts with God, Jesus Christ and the wide range of divine and good spiritual Beings - is a weak, fake Christianity - because it is spiritually dead.
Therefore, the only way actually to be a Christian is to take the risks of being deceived.
And to have faith that anyone who is genuinely motivated to God and Jesus Christ will be able to receive the necessary divine corrections, when things go wrong.
(When, not if, things go wrong.)
Now that traditions of Spiritual discipleship are broken, and now that Men have no good churches upon which faith can be pinned; and when our consciousness has become individual and agentic, rather than being immersed in a group (so that Christians must take personal responsibility)...
We can be sure - 100% confident - that God our Heavenly Father and the Creator - has ensured that every single person is, nonetheless,able to get the experiences and guidance he needs for attaining salvation and spiritual development.
If individual spiritual knowledge and mystical experience are indeed a necessary part of being a Christian, as was believed by the Eastern Orthodox for nearly 2000 years - then we can be sure and confident that this has been made possible.
Possible for me, and for you. So; if you do not already know this by experience, than it is time you found out (that is; if you desire to be and remain Christian).
To summarize: There is no safe way to be a Christian; therefore the danger of spiritual scaremongering is considerable, and safety-first-ism must be rejected - since the sanction for yielding to spiritual scaremongering is to become first a second-hand Christian, then (because that is so feeble and easily corruptible) not-at-all.
One who rejects personal discernment and responsibility and seeks safety in external institutions and rules - will simply not be a Christian before very long, will be led by the nose away from Jesus Christ.
Remember: This is (here-and-now) a world where all major institutions (national and global - including the churches) are under overall-demonic control.
Demons want all religion to be mediated by human institutions, because demons can control institutions.
Surely that is obvious?
Thus; all Christians need direct spiritual contact with - and guidance from - the divine and all possible Beings of Good; and must therefore take courage, take the risks - in a spirit of trial-and-error; while being always open to correction by "divine-feedback" (which will me made available): and ready for repentance.
Note added: I suppose I should say again what I have already stated so many times: which is that I think the current situation is that many (most? all?) real Christians have actually already started doing exactly what I recommend - have used personal discernment and taken personal responsibility for their Christian faith, including their choice of denomination and church, and which "authorities" to follow in that particular church. But... Because this has been unconscious, hidden from their own awareness; they have not acknowledged explicitly to themselves that this is what they have actually done -- and instead they pretend/ assert that their choices were actually compelled by "evidence", "reason", "logic" or some such external and supposedly-objective source (for which they, personally, eschew responsibility for choosing; claiming necessity). These are living in a situation of Bad Faith by denial of what is true. Since such a situation is fundamentally incoherent; therefore their Christianity is weak - and readily corrupted or diverted. I suspect that something of this kind is responsible for the incremental loss of once-real Christians, year by year, as they fail one or another Litmus Test; become this-worldly in their primary orientation and aspirations; or fall into an externally-controlled form of second-hand Christianity that presages de facto exit from the faith.
