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)

In addition to the Gospel of the Lord you'll also read in their original, unedited form Galatians, 1st and 2nd Corinthians, Romans, 1st and 2nd Thessalonians, Laodiceans, Colossians, Philemon and Philippians. That is the entirety of the first Christian bible as it was gathered and transcribed in 144 A.D. and as it is now. Numbered chapters and verses in standard bible format.
