Any entity you truly believe is TRUE “one and only, truest, highest” god automatically becomes more powerful in your world, in that period of time, than anything else that can affect you, this is referenced in the PGM & Hindu prayer where the mage/devotee, who may otherwise be a polytheist, praises one entity as the Highest - then magickally, you can merge with them as well, to act with(in) their current of power.
This was the great con trick of the monotheistic faiths, to both steal that alignment of the person’s inner Creatior and hang onto it - meanwhile, magicians struggle with it because achieving that level of immersive devotion is hard, especially for people who don’t have close loving relationships with entities.
I have been researching why Catholicism has saints on the order of magnitude it does, the fact they have this model of human AS miracle worker, working in such close alignment with god whilst embodied (as well as after death) seems to be their key.
This bears so little resemblance to the “you may not use graven images” parasitism that lies at the core of the Abrahamic sects it is in many ways a different beast entirely, a worship and embodying of Source in aspects AS love, mercy, etc, and VIA human intervention.
I mean that’s my finding anyway, and no offence intended to our Catholic members.
