Other scholars have said that leaders in the Early Christian Church made changes to the Gospel writings. These changes are said to have happened at different times, in different ways and for different reasons. For example, one story was left out of many old versions of the Gospels. It is about Jesus rescuing a woman who had committed adultery (had sex outside marriage) and was about to be killed. St. Augustine of Hippo, (354-430 AD) wrote that this was probably was left out because some church leaders thought the story might cause people to act in a sinful way. This story is in all modern Bibles and is thought to contain very important teaching for Christians. Other differences that can be found in versions of the Gospels are mostly small and do not make a difference to what is known about the life of Jesus and his teaching.
