The beginning of wisdom is the fear of the Lord. For where there is fear, there the commandments are kept; where the commandments are kept, there is the flesh purified—that cloud which envelops the soul and prevents it from seeing clearly the Divine ray; where the flesh is purified, there light springs forth, and the shining of the light fulfils desire above all desires.
One should not ponder divine matters on a full stomach, say the ascetics. For the well-fed, even the most superficial secrets of the Trinity lie hidden.
If a person swallows too much food, he is inviting impure thoughts. If he mortifies the stomach, he is creating pure thoughts. Often a lion if it is caressed becomes domesticated, whereas the more you coddle the body, the more it goes wild.
The belly when filled with all kinds of food gives birth to seeds of wantonness, nor can the mind, when choked with the weight of food, keep the guidance and government of the thoughts. For not only is drunkenness with wine wont to intoxicate the mind, but excess of all kinds of food makes it weak and uncertain, and robs it of all its power of pure and clear contemplation. The cause of the overthrow and wantonness of Sodom was not drunkenness through wine, but fullness of bread. Hear the Lord rebuking Jerusalem through the prophet. 'For how did thy sister Sodom sin, except in that she ate her bread in fullness and abundance?' (Ezek. xvi. 49)
Unless curbed by the fear of God that accompanies the practice of the virtues, spiritual knowledge leads to vanity; for it encourages the person puffed up by it to regard as his own what has merely been lent to him, and to use his borrowed intelligence to win praise for himself. But when his practice of the virtues increases concomitantly with his longing for God, and he does not arrogate to himself more spiritual knowledge than is needed for the task in hand, then he is made humble, reduced to himself by principles which are beyond his capacity.
It is not food that is evil but gluttony; not childbearing but fornication; not money but cupidity; not glory but vainglory. If this be so there is no evil in anything that is, except wrong use, which results from our mind neglecting to cultivate our nature (the powers of the soul, and their right direction).
What does it mean to be as wise as a serpent? When a serpent is attacked, it is willing to have much of its body severed, as long as it saves the head. So to be wise as a serpent means to be willing to lose everything - your wealth, your reputation, your friends - as long as you save your faith. Your faith is your head, by which you learn all truth; and by that truth your soul is set free. We should, however, recognize that the wisdom of the serpent is not enough; we must be honest and innocent as doves. Indeed it is the combination of wisdom and innocence that creates virtue. The person who is wise as a serpent can sustain the most terrible attacks and still continue to flourish as a disciple of Christ. The person who is innocent refuses to retaliate against those who make the attacks. To be as innocent as a dove means never to take revenge on those who wrong you or undermine you. Unless wisdom is tempered by innocence, one attack provokes another, and conflict continues without end. Unless innocence is tempered by wisdom, a person is so vulnerable that he will not even survive a single attack. Rest assured that no one can ever take away your faith; your wisdom guards against that. But be careful never to bear a grudge against anyone who does you wrong.
The one who engages in a pursuit of wisdom out of devotion and stands prepared against the invisible forces should pray that both the natural discernment (with its proportionate light) and the illuminating grace of the Spirit remain with him. The former trains the flesh in the acquisition of virtue through asceticism while the latter illuminates the mind to select the companionship of wisdom before all others, according to the Scripture, 'He works the destruction of the strongholds of evil & of every pretension which raises itself up against the knowledge of God' (2 Cor. 10:5).
To those who do not long for it, wisdom is fear, because of the loss which they suffer through their flight from it; but in those who cleave to it, wisdom is loving desire, promoting an inner state of joyous activity. For wisdom creates fear, delivering a person from the passions by making him apprehensive of punishment; and it also produces loving desire, accustoming the intellect through the acquisition of the virtues to behold the blessings held in store for us.
