This applies even when such 'charitable' activity is genuine, as it usually is not: when the poor being fed really are poor; when genuine peace is being promoted rather than, in fact, war supported; when it is nature genuinely is being protected, rather than than funding multinational fake-sustainable technologies, etc.
I mean that Christians ought to stop trying to help people physically, materially; to cease aiming at a happier and healthier world; to give-up on plans to diminish here-and-now human suffering caused by social problems and injustices.
We have reached a situation from which Christianity must detach itself entirely from all such worldly generic duties, projects etc. - because these will be used against Christianity by Antichrist powers, and will always be expanded to crowd-out the genuine spiritual and next-wordly orientated duties.
This-world and the here-and-now will always - and esepcially to the typical modern mind - seem primary, urgent and imperative; compared with the easy way that next-word and eternal requirements can be delayed, postponed, and made secondary.
From where we now are, with the priorities and motivations and pressures that we now have; Christians should not acknowledge that any worldly actions are specifically Christian and mandatory to Christians.
Of course, we will all continue personally to do specific acts as a matter of our personal love, sense of duty etc - but these cannot be allowed to be imperative as abstract generalizations.
Churches need to do the same; and ought to focus primarily on whatever they regard as spiritual imperatives; or else we will continually repeat the 2020 situation in which the major churches all ceased to offer their spiritual services, while continuing their social services.
As one representative example:
In April of 2020 during the birdemic lockdowns; The Church of England's churches were allowed (by the Bishops' instructions!) to open and be used for use as food banks and "peck" centres, while all sacramental activity in the same buildings was forbidden. Analogous actions were taken by all major "Christian" churches - revealing their true priorities were almost exclusively material, expedient, and totalitarian-compatible.
The only way out and forward from burial beneath the vast complex of wrong motivations and false priorities and confused intentions that led to such appalling practices (in so many churches): is a clean break.
Only from a Ground Zero position of complete spiritual freedom from the currently suffocating network of worldly-entanglements and social-responsibilities; can properly Christian motivations be rediscovered and renewed.
Only after we have solidly established the priority of the spiritual, may we then choose to rebuild a selective and effective concern with the material.
