Catholicism/Orthodoxy are fully integral systems of mystical training and initiation. Both are highly related to Hermeticism, and scholars such as David Litwa (if I recall correctly, might be someone else) make a pretty solid argument that Hermeticists regarded Christ as the Logos and Savior.
This just sounds to me like the typical behavior of Christians, mixing their faith into everything to "make it ok for them to do it" or to "assimilate people into the faith". A good example is Christmas. There is no proof that Jesus was even born on the 25th of December and it's more likely that date is connected to some pagan day of significance (among all the other pagan practices that have been melded into the holiday as if it's Christian - Mistletoe, Yule Logs, Evergreen Trees, Winter Solstice, etc).
Isn't magic of any kind supposed to go against the Christian faith?
A lot of religions just seem to have "stolen" the stories of older myths and repurposed them into their doctrine (Christianity especially). Let's not even go into all of the obvious plagarization between the story of Jesus and the Story of Mithra. Both had a "virgin" birth, both had 12 companions, and while Christmas is Dec 25th, the Roman
Dies Natalis Solis Invicti (Unconquered Sun) festival, linked to Mithras/Sol, was also celebrated then. The story of Mithra is significantly older than the story of Jesus btw.
Let's not even go into the history of the Catholic faith at one point accepting monetary donations from people for the purpose of helping dead relatives get into heaven (and get out of purgatory faster). Yeah you'll say those were just "corrupt people abusing the faith" and they weren't "real catholics", but that's just a "no true scotsman" fallacy. It's too convenient that every bad Christian/member of any religion get's their membership revoked as soon as something bad about them is publicly known.
Do I even have to mention the well known pedophilia problem?
Honestly, one could choose a better faith than Catholicism as an alternative to occult practice. I'd probably go with Tibetan Buddhism, as the minor abilities you can gain through the practice are actually researched, tested and documented (Tummo is a good example).
My point still stands. Show me one person who has actually done anything with Bardon's system
I think you are missing the point. Nobody with any real powers would be stupid enough to come forward and out themselves.
What even awaits you in that scenario:
Being kidnapped by your government for research and experimentation?
Being killed by some secret organization dedicated to keeping knowledge like that a secret?
Having your family be held ransom while you are blackmailed into using your abilities for someone elses goals?
Nobody is ever going to publicly do anything with any occult system, because anyone intelligent enough to progress in the training to gain the abilities, would also be intelligent enough to know that they have to keep those abilities a secret.
I've seen miracles accomplished by very simple prayers by simple people
Peoples minds play tricks all the time, and I doubt those miracles were scrutinized in any real way.
and hundreds of thousands of people can attest to the healings wrought at Lourdes and the sacred wells in the British Isles
Eye witness testimony is not really trustworthy at all, especially when people want to believe something.
It's better to stick to something that is within your cultural frame of reference rather than jumping around all over the place to Russian Orthodoxy, Hinduism, Buddhism, Asatru, what have you.
No, it's better to choose the better offer. There's no reason to not learn a new langauge and/or culture, and even immigrate to a new country, if what it offers you seems more enjoyable and worthwhile to you (especially if it offers you more in benefits).
Now I think I'll end this here because this back and forth would never end and there's not point in really arguing this. We'll both find out whether or not our chosen paths were worth it in the end.
