Israelite Degrees

Isrealites don't have Degrees like other Adept Orders. Instead, they have a system of sacrifice. By sacrificing on a weekly or daily basis, an Israelite gains powers. Normally this arrives in the form of grace and luck (for role-playing purposes, treat this as the minor power of the Order of Chosen). 
Significant sacrifices may warrant totally new but temporary powers, usually things like healing, changes in weather, curses on agents of the Darkness, etc. The exact form of any power given in return for sacrifice is ultimately in the hands of the Storyteller but the effects should be roughly equal to the cost of the sacrifice offered. 
Remember, however, that God is not just some cosmic pawn shop owner. As a Storyteller you are perfectly within your (Biblical) rights to give Israelite Adepts nothing if you feel they have become entitled and believe God somehow owes them this. Or you may tell them God wants a greater sacrifice - better faith and morals.
