He lies in the manger, but contains the world;  He nurses at the breasts, but feeds the angels;  He is wrapped in swaddling clothes, but vests us with immortality;  He found no place in the inn, but makes for Himself a temple in the hearts of believers.
  In order that weakness might become strong, strength became weak.
   -  Augustine, Sermon 190, 4

Prayer:  Mu faith prays to You, Lord, the faith You gave me, and inspired in me by the Incarnation of Your son and the mission of Your preacher. - Confessions 1, 1
