I'm... not satisfied with how faith and magic is intertwined in Shadowrun. I know it's not even a secondary focus, but it's one of the facets of the world and the sixth world. I don't like the Street Magic portrayals of faith-magic traditions, or rather I don't agree that they'd believe it's divinely inspired (whoever their god is). It's clear that those traditions aren't just the priesthoods of their religion either so... yeah.
The Protestant Tradition
Concept: Not all Christian Magicians follow the Christian Theurgy path, with its mixture (some say compromise) of qabbalism and cosmology. An alternative path, colloquially known as the "Protestant Tradition", mixes the "clarity" of Chaos Magic with the "convictions" of believers.
Combat: Guardian
Detection: Guidance
Health: Water
Illusion: Air
Manipulation: Man
Drain: Willpower + Intuition (Progressive) / Willpower + Logic (Conservative)
Chaos magic was strangely palatable for the small number of Christians remaining in the Sixth World. Shamanism and hermeticism carried all the baggage of sorcery that had embedded itself in the faith's inherited psyche. It didn't help that Black Magic, Wicca, and Witchcraft "traditions" not only became popular but were no longer easily dismissed.
The so-called "Protestant Tradition" is not a direct reference to the Protestant subsect of Christianity, but rather because it mimicked (to a superficial degree) the reaction to the orthodoxy and established practicies of the time. Ironically, Christian Theurgy was viewed as too tied up with idolatrous practices to be accepted by evangelicals, baptists, and methodists that the Awakened in their congregations make up the bulk of the Protestant magical tradition.
Magic, like technomancy, is just another result of the fallen state of the world. While there were calls to abstain from Magic use, it is clear that Magic is just another form of science. It's oddly the most secular of all the faith-based traditions in existence as it actively seeks to distance the magical from the divine. Rather, the believers believe that faith is in how you do things not what the thing is.
Practicioners, however, vary on this. They commonly summon Guardian spirits for protection and most take the form of white-robed, winged angels while Guidance spirits take the form of the prophets in the Bible and some of Jesus' apostles. These are viewed as the summoner's own psyche at work and not divine manifestations. Some churches require Magician Pastors to summon Guidance spirits to deliver the sunday sermon, an isolated practice that has thrown the remaining believers into contention.
Further still, the group is divided between two parallel paths. Conservatives believe in dutiful study and rather rigid interpretations of the Bible. They do not lack passion in their spellcasting, and many have observed the simple elegance of their woven mana. Their emphasis is on careful study and direct appication: both of the Bible and of magic (or whatever field one is in, many conservatives are medical doctors, engineers, and so on).
The progressives are a bit less structured in their exploration of their talent. Their Biblical interpretations are less rigid, but also sometimes less cohesive and prone to unfounded claims. This subpath is far more diverse but also more active. Most of the current generation are well educated biblically and its Awakened members are often in the slums and worse parts of the cities.
As a whole, they've been dubbed "Street Prophets" and the more conservative of their brothers and sisters are dubbed "Street Professors".
