John Chrysostom, on Gal 4:8

“But then indeed, not knowing God, you served them, who, by nature, are not gods.”

“Here turning to the Gentile believers he says that it is an idolatry, this rigid observance of days, and now incurs a severe punishment. To enforce this, and inspire them with a deeper anxiety, he calls the elements "not by nature Gods." And his meaning is,-Then indeed, as being benighted and bewildered, ye lay grovelling upon the earth, but now that ye have known God or rather are known of Him, how great and bitter will be the chastisement ye draw upon you, if, after such a treatment, ye relapse into the same disease. It was not by your own pains that ye found out God, but while ye continued in error, He drew you to Himself. He says "weak and beggarly rudiments," in that they avail nothing towards the good things held out to us.”
