Others, like Bahamut flares, or the various Salvage mob AoEs like Mdkuser alluded to, are a function of both the monster's stats and the player's stats, so higher player INT lowers the damage to varying degrees.
So, in short answer to anathema directly. It depends on the WS in question, and it doesn't give you "magic defense" per say but it does adjust the base damage formula for the WS in question when it does affect things. Not sure about resist rates.
