St Theodoros the Great Ascetic: spiritual knowledge is born from faith...

We have been taught that dispassion is born from self-control and humility, while spiritual knowledge is born from faith. Through these the soul makes progress in discrimination and love. 

And once she has embraced divine love, she never ceases to rise towards its height on the wings of pure prayer, until she comes "to the knowledge of the Son of God", as St Paul says, "to a perfect man, to the measure of the stature of the fulness of Christ" (Eph 4:13).
