Wisdom of Solomon 13:5
1 For all people who were ignorant of God were foolish by nature; and they were unable from the good things that are seen to know the one who exists, nor did they recognize the artisan while paying heed to his works; 2 but they supposed that either fire or wind or swift air, or the circle of the stars, or turbulent water, or the luminaries of heaven were the gods that rule the world. 3 If through delight in the beauty of these things people assumed them to be gods, let them know how much better than these is their Lord, for the author of beauty created them. 4 And if people were amazed at their power and working, let them perceive from them how much more powerful is the one who formed them. 5 For from the greatness and beauty of created things comes a corresponding perception of their Creator. 6 Yet these people are little to be blamed, for perhaps they go astray while seeking God and desiring to find him.
Athanasius Against the Heathen 44:3
For as by His own providence bodies grow and the rational soul moves, and possesses life and thought, and this requires little proof, for we see what takes place — so again the same Word of God with one simple nod by His own power moves and holds together both the visible universe and the invisible powers, allotting to each its proper function, so that the divine powers move in a diviner way, while visible things move as they are seen to do. But Himself being over all, both Governor and King and organising power, He does all for the glory and knowledge of His own Father, so that almost by the very works that He brings to pass He teaches us and says, By the greatness and beauty of the creatures proportionably the maker of them is seen.
Notes and References
"... For many Christian authorities the criterion for a book’s inclusion in the canon depended not on the language of composition, but on whether it was normative and authoritative for doctrine and public reading. Yet books that fell outside this category could still be canonical at a lower level, and used for private reading among Christians (compare Tertullian, Cult. fem. 1.3: Gallagher 2012: 20–1), and so were certainly not banned or ignored. Even Athanasius of Alexandria, whose festal letter of 367 ce is often held to demarcate a Christian canon, notes that though certain books are not canonical (οὐ κανονιζόμενα μέν), they were authorized by tradition (τετυπωμένα δὲ παρὰ τῶν πατέρων) for reading to recent converts. For Athanasius these works included Wisdom of Solomon, Sirach, Judith, Tobit, and also Esther, while with most other authorities he included both Esdras A and B in the Old Testament canon ..."
