"And as, my brethren, the time for keeping this festival is approaching, let us consider our duty in the true observation thereof, of the right way for the glory of God, and the good of immortal souls, to celebrate the birth of our Lord Jesus Christ; an event which ought to be had in eternal remembrance."
From Martin Luther (page 26)
"We must both read and meditate upon the nativity. If the meditation does not reach the heart, we shall sense no sweetness, nor shall we know what solace for humankind lies in this contemplation. The heart will not laugh nor be merry. As spray does not touch the deep, so mere meditation will not quiet the heart. There is such richness and goodness in this nativity that if we should see and deeply understand, we should be dissolved in perpetual joy."
