Which one of the apostles was not Jewish? It is they who wrote scripture under the inspiration of the Holy Spirit. Peter called Paul's writings scripture. You can play all the silly word games you want but it was God who told us the Jews were entrusted with His word. Catholics changed, twisted, and added words to scripture.
Luke was Greece. Some say he was an Hellenic Jew, many think he was not.
From Wikipedia:Luke the Evangelist (Ancient Greek: Λουκᾶς, Loukás) is one of the Four Evangeliststhe four authors of canonical Gospels of Jesus Christ. Luke was a native of the Hellenistic city of Antioch in Syria. The early church fathers ascribed to him authorship of both the Gospel according to Luke and the book of Acts of the Apostles, which originally formed a single literary work, referred to as Luke-Acts. Prominent figures in early Christianity such as Jerome and Eusebius later reaffirmed his authorship, although within scholarly circles, both secular and religious, discussions have taken place due to the lack of evidence as to the identity of the author of the works.
The New Testament mentions Luke briefly a few times, and the Pauline epistle to the Colossians refers to him as a doctor; thus he is thought to have been both a physician and a disciple of Paul. Christians since the faith's early years have regarded him as a saint. He is believed to have died a martyr, although accounts of the events do vary.
Little is known about the author of the Book of Revelation.
The Book of Revelation, often known simply as Revelation or The Apocalypse, is a book of the New Testament that occupies a central place in Christian eschatology. Its title is derived from the first word of the text, written in Koine Greek: apokalypsis, meaning "unveiling" or "revelation". The Book of Revelation is the only apocalyptic document in the New Testament canon (although there are short apocalyptic passages in various places in the Gospels and the Epistles).[a]The author names himself in the text as "John", but his precise identity remains a point of academic debate. Evidence for identifying the author as John the Apostle comes from second-century writers such as Justin Martyr, Irenaeus, Melito the bishop of Sardis, and Clement of Alexandria and the Muratorian fragment.[1] Other scholars oppose this view,[2] proposing that nothing can be known about the author except that he was a Christian prophet.[3] The bulk of traditional sources date the book to the reign of the emperor Domitian (AD 81-96), and the external and internal evidence tends to confirm this.[4]
Even the other books usually credited to the Apostle John have been the subject of debate over authorship since 200 AD. For more on these questions see the full article on John the Apostle.
We simply don't really know with any certainty who wrote most of the Bible.
