Today is the feast of St. Athanasius the Great, Patriarch of Alexandria, Doctor of the Church, although, of course, liturgically Sunday takes precedence. From his Against the Heathen, Part III, section 42:
The holy Word of the Father, then, almighty and all-perfect, uniting with the universe and having everywhere unfolded His own powers, and having illumined all, both things seen and things invisible, holds them together and binds them to Himself, having left nothing void of His own power, but on the contrary quickening and sustaining all things everywhere, each severally and all collectively; while He mingles in one the principles of all sensible existence, heat namely and cold and wet and dry, and causes them not to conflict, but to make up one concordant harmony. By reason of Him and His power, fire does not fight with cold nor wet with dry, but principles mutually opposed, as if friendly and brotherly combine together, and give life to the things we see, and form the principles by which bodies exist. Obeying Him, even God the Word, things on earth have life and things in the heaven have their order. By reason of Him all the sea, and the great ocean, move within their proper bounds, while, as we said above, the dry land grows grasses and is clothed with all manner of diverse plants. And, not to spend time in the enumeration of particulars, where the truth is obvious, there is nothing that is and takes place but has been made and stands by Him and through Him, as also the Divine says, In the beginning was the Word, and the Word was with God, and the Word was God; all things were made by Him, and without Him was not anything made.
