Pretty much everything listed here shows the solid backing of real world religious information separating spells and sorcery. However, there is also a solid basis of the use of shamanism, ancestral worship, and placation of other creatures in the same period. Look into the concept of the Elf Charm, or similar early Proto-Christian and Druidic minglings of local ancestral and spirit placation = Divine Magic.
Personally I like some of the concepts presented across other stories and books eries. I 'm thinking most of A Song of Ice and Fire and its presentation of the Maegi, Blod Priests, Greenseers, and Pyromancers, and Maesters as a mixture of common woodscraft and medicine combined with the occasional use of mysticism. Maesters can heal with poultices, draughts, etc. but there are also those who bear the Valyrian steel link such as the Magus. I also like the idea upthread regarding the Schools of Roke, or even that there are spells and skills that will be more useful to some than others. How useful is fireball to an urban sorcerer in the midst of large flammable structures filled with enough commoners to scream "BURN HIM!" and make his studies end abruptly?
How about a battlemage? You would be happy to have the ability to heal. Perhaps even 'evil' spells could be used by priests (creating undead through the 'breath of life' in ASOIAF comes to mind, or the calling of demons to commune with by numerous 'good' wizards and even traditional 'priests' in too many sources to count).
To sum up, there are precedents in history and fantasy that blur the line between magic both Arcane and Divine, along with magic and science. It would make more sense in a game where you are not going to be very godsheavy to use this blurring to your advantage. YMMV, but if you don't make it easy to munchkin up the CoD greatest hits for your mage, and change around anything that seems to be too heavy, be my guest
