9. When choosing a director, be careful to select one who has the necessary qualifications. He should be not only virtuous, but prudent, charitable and learned. St. Francis de Sales gives the following opinion on the subject: “Go,” said Tobias to his son, when about to send him into a strange country, ‘go seek some wise man to conduct you.’ I say the same to you, Philothea. If you sincerely desire to enter upon the way of devotion, seek a good guide to direct you therein. This advice is of the utmost importance and necessity. Whatever one may do, says the devout Avila, he can never be certain of fulfilling God’s will, unless he practice that humble obedience which the saints so strongly recommend and to which they so faithfully adhere. And the Scriptures tell us: ‘A faithful friend is a strong defence: and he that hath found him, hath found a treasure: ... a faithful friend is the medicine of life and immortality: and they that fear the Lord shall find one.’ (Ecclesiasticus, c. VI, vv. 14-16.) But who can find such a friend? They that fear God, the Wise Man answers—that is to say, those humble souls who ardently desire their spiritual progress. Since it is so essential, then, Philothea, to have a skilful guide in the devout life, ask God fervently to give you one according to His Heart, and rest assured that when an angel is necessary to you as to the young Tobias, He will give you a wise and faithful director. In fact, the selection once made, you should look upon your spiritual guide more as a guardian angel than as a mere man. You place your confidence not in him but in God, for it is God who will lead and instruct you through his instrumentality by inspiring him with the sentiments and words necessary for your guidance. Thus you may safely listen to him as to an angel sent from heaven to lead you there. To this confidence, add perfect candor. Speak quite frankly and tell him unreservedly all that is good, all that is evil in you, for the good will thus be strengthened, the evil weakened, and your soul shall thereby become firmer in its sufferings and more moderate in its consolations. Great respect should also be united with confidence and in such nice proportion that the one shall not lessen the other: let your confidence in him be such as a respectful daughter reposes in her father, your respect for him such as that with which a son confides in his mother. In a word, this friendship, though strong and tender, should be altogether sacred and spiritual in its nature.
