This quite is from the Qu'ret al-Yezid (https://www.joyofsatan.org/www.angelfire.com/empire/serpentis666/QuretAlYezid.html), and it was originally meant for the yezidi people at a time when their people were under heavy persecution of the surfacing enemy "religions". So the context of this quote is rather in comparison to the false gods of the enemy, not in comparison to the other Gods who are at Satan's side.
