Also,
magical life (a.k.a. Ally spirits, Watchers) is created in the SR universe on a daily basis. Most religions have made their arrangements with this fact - the Chuch mostly endorses it if certain practices are applied, and even has orders dedicated to 'white' magic. Many protestant or independent wonder healers and preachers are supposed to be awakened, and many non-catholic churches are much more open towards magic (the Orthodox being among these).
Islam is very permissive with spirits anyway - there are very interesting rulings in islamic jurispondence about spirit/human marriages, for instance (really,
click here for a fatwa on this matter; the gist: it is usually agreed upon that this is forbidden but the Sufi and Yemenite think otherwise), and Jinn - spirits - are considered to be an intelligent creation on equal level with humanity by the Quran. It is worth noting that, with that Fatwa, despite the con side being vastly overrepresented, only the Hanbali school agrees, which is the prevalent school of islamic law in Saudi Arabia and *nowhere else*. All other islamic schools seemingly would not mind you marrying your ally spirit (provided you free it first, see the ban on marrying slaves). Whether or not some baptist outfit in the Midwest or some Wahhabist terror commandos in Iran have their knickers in a knot about spirits, nobody cares.
The German Catholics are rather strict and only recognise theurgic rites as non-diabolic, and there certainly are some more radical islamist schools that frown upon spirit creation (a.k.a. Ally spirits), but those are the fringe. Judaism is the basis of SR hermeticism, so I think it is fair to assume no Rabbi will raise an eyebrow on the creation of an Ally spirit.
Also, Israel is pretty deep in cloning and AI/drone research in SR, so they're unlikely to protest, except maybe for some weirdo ultra faction.
Most Asian religions are probably oblivious to this or work this in somehow, being essentially polytheist and thus much less dogmatic. I wouldn't know of any ban on creation in either Hinduism, Buddhism or Chinese Spirituality.
So anyway, you can well build such a magical group. Just don't claim anybody would care.
