You seem to be missing the overall point. A New Testament author may quote a source without accepting it as Scripture.
Also it is unlikely that Paul is the author of the book of Hebrews for a number of reasons. A quick check of early church history will support that point. As Origen points out:
"Who wrote the epistle is known to God alone: the accounts that have reached us suggest that it was either Clement, who became Bishop of Rome, or Luke, who wrote the gospel and the Acts."
And those two are not the only names that have been suggested.
You’re missing the point. When people say the Apocrypha is not scripture, they say that the main REASON WHY is because the New Testament does not reference it. But it does.
And Hebrews 11 references 2 Maccabees as a part of Biblical history. I went to grade school and I know what context is. And the context of Hebrews 11 is that it’s part of the Bible. I’ve always gotten that impression, even when I didn’t know who the tortured men are (since I was using a Bible that was missing the apocrypha and marginal notes).
The identity of the author of Hebrews is not the point. You’re barking up the wrong tree on that one. Who cares if it was written by Paul, Barnabas, Clement, Luke or someone else? Point is, it’s scripture, and the author was inspired. That’s all that matters.
You quote Origen in regards to who the author of Hebrews is. Why don’t you quote Origen when he called 2 Maccabees holy scripture?
Origen de Principiis book 2 ch 1.5 (185- 254ad)
"But that we may believe on the authority of holy Scripture that such is the case, hear how in the book of Maccabees, where the mother of seven martyrs exhorts her son to endure torture, this truth is confirmed; for she says, "I ask of thee, my son, to look at the heaven and the earth, and at all things which are in them, and beholding these, to know that God made all these things when they did not exist."

What caused Origen to think Maccabees is scripture? Origen was discipled by Clement of Alexandria. What caused Clement to accept Maccabees as scripture? What caused the churches in Alexandria to accept it as holy scripture? Why did the church councils of Rome, Hippo, and Carthage declare it to be holy scripture?
Clearly, the early church accepted it LONG before the council of Trent in 1546.
