If, as we have said, we commemorate each of the saints with hymns and appropriate songs of praise, how much more should we celebrate the memory of Peter and Paul, the supreme leaders of the pre-eminent company of the apostles? They are the fathers and guides of all Christians: apostles, martyrs, holy ascetics, priests, hierarchs, pastors and teachers. As chief shepherds and master builders of our common godliness and virtue, they tend and teach us all, like lights in the world, holding forth the word of life (Phil. 2:15–16).
Their brightness excels that of the other radiantly pious and virtuous saints as the sun outshines the stars, or as the heavens, which declare the sublime glory of God (cf. Ps. 19:1), transcend the skies. In their order and strength they are greater than the heavens, more beautiful than the stars, and swifter than both, and as regards what lies beyond the realm of the senses, it is they who reveal things which surpass the very heavens themselves and indeed the whole universe, and who make them bright with the light “in which there is no variableness neither shadow of turning” (cf. Jas. 1:17).
Not only do they bring people out of darkness into this wonderful light, but by enlightening them they make them light, the offspring of the perfect light, that each of them may shine like the sun (Matt. 13:43), when the author of light, the God-man and Word, appears in glory.
