On the other hand, if someone were to reverence the sign of the Cross without the Lord's Name written upon it, he could justly be accused of doing something incorrect. Since 'at the Name of Jesus every knee should bow, of things in Heaven, and things in the earth, and things under the earth' (Phil. 2:10), and the Cross bears this venerable Name. How very foolish not to bow the knee at Christ's Cross!
St. Gregory Palamas, Homily 11,
On the Precious and Life-giving Cross
