If the Demigod actually belongs to the Temporal Wizard O.C.C. (which I assume is the case since the character has been in service to a Temporal Raider), then the character will learn spells normally for that O.C.C., progressing according to the rules given in Rifts England.
If the Demigod chose Temporal Magic as his or her divine power, then you have a problem. Technically the character would not learn any Temporal Magic spells until reaching 7th level, and it is debatable whether the character could learn conventional magic spells at all. In order to make this workable, I would reduce the level of Temporal Magic spells by six for the purposes of which ones are gained at each level, so at first level the Demigod would know 7th level Temporal Magic (and possibly all 1st level Ley Line Walker/Wizard spells). Also, because the Demigod's magic powers are inherited in this case, servitude to a Temporal Raider would be unnecessary, and I would not give the character any of the bonuses or penalties of servitude.
