Hi, friend, if I may, a word on the origin of the Bible. A study of church history will reveal that the "capital" of Christianity was moved from Palestine to Rome in the 4th century when Christianity was legalized by Emperor Constantine. Very quickly, many men - who made sure to hide their "faith" from the authorities when so many of their brethren deemed it an honor to perish for the cause of Christ - began pushing their way to the forefront as these religious opportunists saw that could safely be done now that Christianity had legal status. They sought the favor of the secular power, which was all to happy to grant to these "Christian" leaders who were so anxious to compromise the purity of the Gospel for ecumenical unity with the pagans of the Empire. An "ecumenical Bible" was commissioned by Constantine for Eusebius, who was a follower of Origen - a straight up occultist and preacher of occult Christian doctrine - using available MSS of the day in that region. About 50 copies were made, were rejected by the early church, and went underground. Incidentally, Codex Sinaticus which was found in 1844 at Sinai to be the oldest MSS and forms the basis for every new Bible version out there today since the beginning of the 20th century, including the JW's NWT, NIV, NASB, TEV, NKJV, etc., is believed to be by many, many authoritative diplomatics none other than one of these 50 corrupt "ecumenical" Bibles of Constantine's day. This is why the new versions of today read so differently from Bibles based on the Textus Receptus Greek, such as the KJV.
Meanwhile, back in Palestine, the purity of the Gospels, the epistles, etc. was kept alive by devout men wholly unconcerned with whatever gain the world might afford them, but only with spreading the truth of Jesus' salvation and His Second Coming, for which we need to prepare. These men lived and worked in that region until Muslims overran Palestine and forced these men to retreat West. With their ancient MSS maintained in the purity of Christ's truth in hand, they settled in Europe and began disseminating for the first time in Europe the unmolested truth of God's Word, which quickly came into conflict with Rome's corrupt MSS. These conflicts eventually led to the Protestant Reformation and the re-establishment of God's true Word on the stage of history, never again to be hidden away from the masses, who were subject to the death penalty for reading or possessing copies of even Rome's corrupt Bible MSS.
Therefore, when speaking of who was responsible for compiling the Bible, it depends upon which Bible is in question: the Bible based on the corrupt MSS of the Western church in Rome or the one based on the purity of God's Word preserved by His own hand. An excellent documentary on YouTube to view more info about this subject is "A Lamp In The Dark: The Untold History of The Bible". Very comprehensive and very well substantiated with facts from history and diplomatics.
