From Bernard of Clairvaux’s Homily II in Praise of the Blessed Virgin (CF 18 A, pp 30-31)
…And the Virgin’s name was Mary. Let us now say a few words about this name, which means “Star of the Sea” and is so becoming to the Virgin Mother. Surely she is very fittingly likened to a star. The star sends forth its rays without harm to itself. In the same way, the Virgin brought forth her Son with no injury to herself. The ray no more diminishes the star’s brightness than doe the Son his mother’s integrity.
She is indeed the noble star risen out of Jacob whose beam enlightens the earthly globe. She it is whose brightness both twinkles in the highest heavens and pierces the pit of hell, and is shed upon earth, warming our hearts far more than our bodies, fostering virtue and cauterizing vice. She, I tell you, is that splendid and wondrous star suspended as by necessity over this great wide sea, radiant with merit and brilliant in example.
O you, whoever you are, who feel that in the tidal wave of this world, you are nearer to being tossed about among the squalls and gales than treading on dry land, if you do not want to founder with the tempest, do not avert your eyes from the brightness of this star. When the wind of temptation blows up within you, when you strike upon the rock of tribulation, gaze up at this star, call out to Mary. When rage or greed or fleshly desires are battering the skiff of your soul, gaze up at Mary. When the immensity of your sins weighs you down and you are bewildered by the loathsomeness of your conscience, when the terrifying thought of judgment appalls you and you begin to founder in the gulf of sadness and despair, think of Mary.
In dangers, in hardships, in every doubt, think of Mary, call out to Mary. Keep her name in your mouth, keep her in your heart. Follow the example of her life and you will obtain the favor of her prayer. Following her, you will never go astray. Asking her help, you will never despair. Keeping her in your thoughts, you will never wander away. With your hand in hers, you will never stumble. With her protecting you, you will not be afraid. With her leading you, you will never tire. Her kindness will see you through to the end.
