Theophilus of Antioch, To Autolycus 2.35
The divine law forbids not only the worship of idols but also the worship of the elements — the sun, the moon, or the other stars — and it forbids worship of heaven, earth, sea, springs, or rivers. Instead, one must worship only the one who is truly God and the maker of all things, doing so with a holy heart and a pure intention.
Greek
Ὁ μὲν οὖν θεῖος νόμος οὐ μόνον κωλύει τὸ εἰδώλοις προσκυνεῖν, ἀλλὰ καὶ τοῖς στοιχείοις, ἡλίῳ σελήνῃ ἢ τοῖς λοιποῖς ἄστροις, ἀλλ᾿ οὔτε τῷ οὐρανῷ οὔτε γῇ οὔτε θαλάσσῃ ἢ πηγαῖς ἢ ποταμοῖς θρησκεύειν· ἀλλ᾿ ἢ μόνῳ τῷ ὄντως θεῷ καὶ ποιητῇ τῶν ὅλων χρὴ λατρεύειν ἐν ὁσιότητι καρδίας καὶ εἰλικρινεῖ γνώμῃ.
