If you're not reading the same bible as the first Christians in 144 A.D. you're reading just another book.

The first Christian bible is not only the foundation of faith that virtually every denomination traces its canonical roots back to - it's also the only place you'll find the gospel preached by Paul the Apostle that he specifically references numerous times: "But I certify you, brethren, that the gospel which was preached of me is not after man. For I neither received it of man, but by the revelation of Jesus Christ." (Galatians 1:8-9)
