According to Shades of Empire Page 56:
"Were this the extent of their activities, the Hedgefolk would not attract so much attention from Witch Hunters and Magisters. Most Cunning Folk also sell an array of potions and talismans of a dubious kind, such as love philtres, lucky charms, protection pouches, and similar items, all of which are deemed to be the province of witchcraft by many overzealous Sigmarites. Worse, a minority—called the Blessed Few by the Hedgefolk— channel magic. Although they believe their powers to be granted by the Gods, Imperial Law does not agree. As far as the authorities are concerned, the Blessed Few are Witches, and when found guilty, they are burned."
So I'm not sure about that. All Hedgefolk are dedicated to some sort of divine entity, some of which we know, some of which we don't. They are not, in fact, a secular entity. Their magic mechanically holds different powers than Divine Magic, but that isn't to say that they're not Cult-ish.
