Actually, Hisalone is correct, but perhaps you are both just talking past each other.
All of the books of the bible (Old and New Testament) were written by Jews (guided by the Holy Spirit (with the possible exceptions of Luke and Acts - as Luke is believed by some to have been a Gentile).
However, Bill is correct that while the OT “cannon” scriptures compiled by Jews (although Bill - on that point, the deutercannonical books were omitted from the Jewish cannon when the cannon was established by the Jews in the early 2nd century), the NT cannon was established (e.g., books identified as scripture) by “Catholics” (by Christians and officially declared at the counsel of Nicea). At that time, the “Church” was the Catholic Church (east and west).
Hopefully that is just a clarification both all as I think you guys were trying to say the same thing.
Blessings,
