72. God created both the invisible and the visible worlds, and so He obviously also made both the soul and the body. If the visible world is so beautiful, what must the invisible world be like? And if the invisible world is superior to the visible world, how much superior to both is God their Creator? If, then, the Creator of everything that is beautiful is superior to all His creation, on what grounds does the intellect abandon what is superior to all and engross itself in what is worst of all – I mean the passions of the flesh? Clearly this happens because the intellect has lived with these passions and grown accustomed to them since birth, whereas it has not yet had perfect experience of Him who is superior to all and beyond all things. Thus, if we gradually wean the intellect away from this relationship by long practice of controlling our indulgence in pleasure and by persistent meditation on divine realities, the intellect will gradually devote itself more and more to these realities, will recognize its own dignity, and finally transfer all its desire to the divine.
Asceticism, a word derived from one which originally described the physical training of an athlete, used to be part of the universal life of all Christians. We recognized, as St. Maximos outlines above, that we must train our nous and break the grip of the passions which enthrall us. Somehow that awareness and practice has been all but lost in modern Christianity. Is it any wonder, then, that we’re spiritually flabby?
