Has the Bible been changed?

The Bible consists of two parts, the Old Testament and the New Testament. The books of the Old Testament were written from about 1400 Before Christ to 400 Before Christ. The books of the New Testament were written from about the year 40 till 90 After Christ.

Old Testament

Almost all written in Hebrew. The Septuagint (LXX) is a Greek translation of the original Hebrew text of the Old Testament in a 200 Before Christ. When you compare this 2200 year old text with present day Old Testament you won’t notice big differences [1]. We can say the Old Testament is very reliable. Christians did also not change the text of the Old Testament, because it was already available as the same book in 200 Before Christ. No significant changes were made to the oldest text of the Old Testament compared with the text we read today.

New Testament

The New Testament consists of a great number of source texts. There are more than 4000 different ancient Greek manuscripts containing all or portions of the New Testament that have survived to our time. These are written on different materials with differences between each other so small that they are not significant, because they will not give another message. Both the authenticity and the reliability of the books of the New Testament may be regarded as finally established [2].


Even secular scholars agree that the Bible is a surprisingly reliable copied document over so many centuries. Comparing copies from the year 300 with copies from the year 1400 will not give meaningful differences. There is no evidence that the Old Testament or New Testament is changed or that significant false messages have been added. Conclusion: Christians have not changed the original Bible.
