By Stephen Freeman, November 19, 2006 [Monday] November 15, the Orthodox Church began its “Winter Lent,” the fast that prepares for the feast of the Nativity. Somewhat similar to Advent, it is the older practice, a full 40-day fast, that reminds us that Christmas, joy that it is, is a foretaste of Pascha. The Cave of Bethlehem reminds us of the Cave of Hades (icons of the Descent into Hell picture the Cave of Hades).
