Unfortunately, the wonder and magnificence of the Incarnation and the subsequent birth of the humble little Christ Child, including study and reflection on these singularly unique and pivotal events in human history, are often displaced by other concerns. Often unrecognized or forgotten is the struggle, the bloodshed, and the extreme labor of the Church over the centuries to guard and transmit the truth of Jesus of Nazareth in its full purity to the entire world.
