Did Paul consider this Greek poem about Zeus to be scripture since he quoted it twice?

[Rudy Can't Fail]

It's "Cretica" by Epimenides

They fashioned a tomb for thee, O holy and high one—
The Cretans, always liars, evil beasts, idle bellies!
But thou art not dead: thou livest and abidest forever,
For in thee we live and move and have our being.

In context, it's addressed to Zeus and Paul quotes it twice. Once in Titus 1:12, "One of themselves, even a prophet of their own, said, The Cretians are alway liars, evil beasts, slow bellies."

The other quote is most interesting, since he applies it to the God he's preaching but the original author is addressing Zeus. It's Acts 17:28-29, when he is saying how the Gentiles may have actually found God already, "That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us: For in him we live, and move, and have our being."

I've always been fascinated by that. Why did Paul lay so much importance on this poem? Did he see it as a kind of scripture? What authority did he believe it had?
Acts is indeed written by Luke but in the passage quoted he is recounting a speech given by Paul.

He was inspired by Zeus to have it appear in the word of that other lesser god.

I think he simply decided to give it authority. He kind of made things up along the way sometimes

Acts was not written by Paul. It was written by Luke.

no, remember that paul was a persecutor of christians before he became a follower of christianity. Go back and rightly divide the word with subject and context, using the earth age. now, you have the answer.
