Preserve your soul, oh! so perfectly from the slightest touch of evil, remembering that the least deliberate venial sin stains it more than we can comprehend. Above all, cherish holy purity, that exquisite ornament of youth, which, like a polished gem, may so easily lose its lustre. Guard the avenues of your soul, your sight and hearing and the other senses, through which contamination from without is always seeking to enter and defile the beauty of God's handiwork. About us is an atmosphere of worldliness, which we imperceptibly breathe in from the words of companions, from the printed page, and the example of the careless. Shun companionship with the frivolous, vanity of dress, and that indiscriminate reading which only feeds an idle curiosity. The theatres of our day are especially dangerous to virtue, and he who stays away from them entirely, will consult his own advantage, as well as please God. In this soft and luxurious age the popular trend is to self-gratification in all its forms. But the true Christian must ever strive against corrupt nature, if he would not be carried away by the stream of voluptuousness. Self-denial is the watchword of Christianity. All are called to the practice of penance in some shape or form, the best usually being the exact performance of duty. The young of school age will find a strong shelter from temptation in the scrupulous and enthusiastic performance of their daily tasks and lessons. That small boy had caught the true spirit, who used to rise early, to prepare himself, as he said, for the "missionary" life, to which he aspired. A material help for boys to prepare for future life, is to serve at the altar. He who sacrifices his morning sleep, overcoming sloth, to minister to the priest at Mass, is already, by a privilege, fulfilling the functions of one of the minor orders, that of the acolyte. The devout server at Mass shares in its graces next to the celebrant, and more than the ordinary faithful who assist at it; and many an altar-boy, as he glided about the sanctuary, mingling with the invisible angels who hovered around the Victim of sacrifice, has felt the seeds of vocation sprouting in his soul. Devotion to the Mother of God should also be a characteristic of youth. She sympathizes with us, as only a mother can, in all our difficulties and trials. She fully appreciates what we have to contend with, she sees our weakness, the strength of our passions, the temptations we encounter, and she is eager to throw about us the mantle of her protection, if we will only ask her. Never a day should pass without our commending ourselves earnestly to her motherly heart, for she is even more interested in our welfare than we ourselves. She is powerful to aid us, since all good things come to us through her; and she will choose for her devout clients the career in which they may best serve God.
