Azazel himself isn't able to resurrect people, that's why he used a being's body (Reaper) who could, also he said that it's like a law to resurrect people using deals.

General MGD 109 has a point, now while celestial beings weren't reproduced by God, they are literally his children, which makes it not metaphorical.
