Holding that God has the character trait of being perfectly loving does not imply the action of perfectly loving, i.e., engaging in the best kind of loving relationship with another.
One may object that this argument depends on an equivocation on the phrase “perfectly loving”. One who thinks that God is a perfect being must hold that God has the character trait of being perfectly loving, but this doesn’t seem to imply the action of perfectly loving (i.e. engaging in the best kind of loving relationship with another) (Lebens and Tuggy 2019).
