"now debunk this " ......

OK.......Hows this....

1/ There is a clue and it is found in chapter 217. The last sentence states that 100 pounds of stone were placed on the body of Christ and this would lead us to believe that the gospel was penned recently: the first use of the pound as a unit of weight dates to the Ottoman Empire in its dealings with Italy and Spain.

2/ ‘In the name of the Lord, this book is written by monks of the high monastery in Nineveh in the 1500th year of our Lord.’ There is not enough space here to go through the grammatical and conceptual errors in detail, but experts in modern Assyrian assure us that they are obvious and quite significant. Apart from anything else, the inscription says ‘book’, but one never refers to a bible in Assyrian with the word ‘book’. The Bible is either referred to as New or Old Testament, or Holy Book. It is quite unlikely that monks could have made such obvious mistakes.

3/ even from an Islamic point of view, the ‘Gospel of Barnabas’ is far from flawless. For example, it says that there are nine heavens and that the tenth is Paradise, while the Qur’an only mentions seven. The Aramaic text states that Mary gave birth to Jesus without experiencing pain while the Qur’an explicitly refers to the pain of childbirth.

4/ The text mentions three armies the Palestine of the time, each of which was made up of 200,000 soldiers. However the entire population of Palestine 2,000 years ago probably didn’t come to more than 200,000 people, according to some scholars.

"In short, all of this leads us to believe that we are dealing with a wonderful fake.
According to some scholars, ‘the gospel attributed to Saint Barnabas was written by a European Jew in the Middle Ages who was fairly familiar with the Qur’an and the Gospels. He mixed facts and elements from both but his intentions are still unknown.’ "

Then there is this.....

"To believe that the Gospel of Barnabas is anything other than a 16th century fraud is an assault on common sense."

Followed by this....

"This Gospel is considered by the majority of academics, including Christians and some Muslims (such as Abbas el-Akkad) to be late and pseudepigraphical; however, some academics suggest that it may contain some remnants of an earlier apocryphal work (perhaps Gnostic, Ebionite or Diatessaronic), redacted to bring it more in line with Islamic doctrine. Some Muslims consider the surviving versions as transmitting a suppressed apostolic original."

Then of course you could make up your own mind by reading it for yourself......
