St. Gregory of Sinai: The passions that pertain to the body differ from those that pertain to the soul . . .

Icon of St. Gregory of SinaiThe passions that pertain to the body differ from those that pertain to the soul; those affecting the appetitive faculty differ from those affecting the incensive faculty; and those of the intelligence differ from those of the intellect and the reason.

But all intercommunicate, and all collaborate, the bodily passions with those of the appetitive faculty, passions of the soul with those of the incensive faculty, passions of the intelligence with those of the intellect, and passions of the intellect with those of the reason and of the memory.
