The Urantia Book
We need to ask how would God speak to humanity if he wanted to communicate with the average person on earth. Would it be beyond our means of understanding like the Urantia book is written or like the Bible is written.
The Urantia book is nothing less than new age gnostic enlightenment with a space age twist. It attracts the pride of man. It is deceptive in its approach by claiming to correct all religious books, as well as challenging God as the author and keeper of His truth found in the Bible. Paul preached the gospel “not with the wisdom of words, lest the cross be made of no effect.” (1Cor. 1:17) “The world through Wisdom did not come to know God.” (V.21) The Urantia’s revelation proposes in the place of the Bibles revelation extra-Biblical and contradictory information, opposing the core doctrines of Christianity.
Galatians 1:8, “but even though we, or an angel from heaven, would preach to you a gospel contrary to that which we have preached to you, let him be accursed.” This book and its authors are cursed according to the Bible. And those who follow its teachings are according to the apostle Paul. The real issue comes down to authority. One trusting a book whose authors are unknown who claim superior knowledge of past events changing the people and places to be what they want. Or do we trust the eyewitnesses and the authors of the accounts of Jesus with its accurate history kept by the Holy Spirit of God. Is it any wonder the Urantia book calls them holy spirit adjusters, since this other spirit wants to revision everything God has said. Reliability of Scripture is denied and challenged. (P. 838)
We know who was the challenger of the word God spoke in the beginning, the same one who has challenged God in this book. Time has not changed his ways.
Since the Urantia book presents a Jesus that is not the same as the Bible, it cannot be God inspired nor accurate on what it adds to the Bible. http://www.letusreason.org/Cults17.htm
