Inasmuch then as our Master knew that if He carved out only one road for us, many must shrink from it, He carved out divers roads. You cannot enter the kingdom by the way of virginity? Enter it then by the way of single marriage. You cannot not enter it by one marriage? By chance you may by means of a second marriage. You cannot enter by the way of continence: enter then by the way of almsgiving: or you cannot enter by the way of almsgiving? Then try the way of fasting. If you cannot use this way, take that--or if not that, then take this.
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.
When thou perceivest that God is chastening thee, fly not to His enemies... but to His friends, the martyrs, the saints, and those who were pleasing to Him, and who have great power [parresian, 'boldness of speech'].
The most important thing in any good effort and the height of all activities is to persevere in prayer, by means of which we can always acquire through supplication the other virtues from God as well.
Monasticism itself is a perpetual labor of conquering passions and uprooting them in order that, being in a pure and immaculate state, one may preserve oneself before the face of God. This, then, is your task! Give your attention to it, and direct all your powers towards it.
