Zeus was the father of the Gods, and the basis of the comment from the Athenian poet Aratus, ca300-250BC, Phaenomena 1:5: “We are his offspring” Acts 17:28 A poem in which Aratus gives an overview of the origins of the stars.
Silas was called (roman) Jupiter, or (greek) Zeus at Lystra Acts 14:12,13 The occupants of Lystra brought oxen and garlands to the gates to offer to the gods. The greek meaning has a father of helps.
Christ had been asked by the Jewish nation who was his father John 8. Christ then demonstrates that the nation had come from the fatherhood of the devil. But his real question was what mother had they come from: for claiming spiritual fatherhood also requires spiritual motherhood. The Jewish nation could legitimately claim fatherhood in Abraham, but they were a nation entrapped in slavery to tasks, and following the spirit of Hagar who mocked at the real spiritual seed, and had circumstances presented would have killed him, in the same way the nation killed his greatest son.
To be a true spiritual son, one has to have the spirit of the Father, Rom 8. And to be attached to that spirit of holiness requires not only faith but a genuine response to the belief that the Father has created something that we cannot do, we are in fact “dead bodies” Rom 4. To be a real son then is not only looking the same, but having the same character.
To be a son of Zeus would mean that Silas was made in the image and likeness of his father, but Paul and Silas had a greater revelation, that of a life more wonderful and satisfying, that was a reflection of the eternal, moral and physical glory of the one “who will become” the Father of lights, the deity who will be to us for mighty ones, and we to him for a people Ex 6:6
