What official statements represent Christianity's position on the Gospel of Barnabas?

Both Christians as well as Muslims scholars, for genuinely valid reasons have already rejected the gospel of Barnabas as forgery. Here are a few of these reasons:

• According to this book, Barnabas was one of Jesus’ original twelve apostles which is not so. Barnabas as an apostle came after the original twelve, and was a fellow missionary with the apostle Paul. In their travels, Paul and Barnabas boldly declared Jesus’ death, resurrection and lordship in the first century. Therefore, this book could not be from Barnabas who was moving with Paul.

• If Barnabas really is the author then it is reasonable to expect that he would be familiar with the basic facts of Jewish life at this time. This is not so as evident from this book itself. This ancient Italian manuscript departs from the teaching of the Qur'an by calling Muhammad the Messiah rather than Jesus.

• The word (Christ) is the Greek translation for the Hebrew word (Messiah). Both these words when translated into English mean the Anointed One or the Chosen One. This word is not an obscure or rarely used word, on the contrary it is one of the most famous words in the Jewish and Christian religions. There is no doubt that a religious Jew like Barnabas would have been very familiar with this word. At the very start of the Gospel of Barnabas Jesus is called the Christ.

“God has during these past days visited us by his prophet Jesus Christ (p.2).”

However, thereafter throughout this book Jesus denies being the Messiah:

“Jesus confessed and said the truth, "I am not the Messiah" (chap. 42).”

It cannot be that Jesus is the Christ and deny being the Messiah when both words mean exactly the same thing. Whoever wrote this book did not know the Greek meaning of the word Christ is Messiah. Barnabas was a Hebrew who lived on the island of Cyprus, a Greek-speaking island, and travelled around the 1st century Greek-speaking world. He was Hebrew, knew Greek, and could not have made this mistake with such a famous word. This another reason that this book could not be from Barnabas of First century.

In chapters 20-21 of this book there is mention about Jesus sailing to Nazareth and being welcomed by the seamen of that town. He then leaves Nazareth and goes up to Capernaum. Jesus went to the sea of Galilee, and having embarked in a ship sailed to his city of Nazareth. ...Having arrived at the city of Nazareth the seamen spread through the city all that Jesus wrought (done) ... (then) Jesus went up to Capernaum (chaps. 20-21).

• Scholars have found a major error in this account because Nazareth was not a fishing village. In fact, it was about 14 km from the Sea of Galilee and situated in the hills of a mountain range. Capernaum was the fishing village that Jesus arrived at with his disciples, not Nazareth. Nazareth and Capernaum were two towns, which Jesus often visited with his disciples therefore any disciple of Jesus would know these towns well. However, the author of this book does not! This casts doubt over the claim that he was a disciple of Jesus. It also puts aspiration on the author that he ever lived in that region. The Gospel of Barnabas makes basic mistakes about the language and geography of the Jewish world in the 1st century A.D. These mistakes have cast doubt over the claim that it was written by Barnabas in the 1st century

• In the news item, they have shown the photographs of the two or three pages of the book where there is a picture of Cross at some places. This is in contradiction to the stated claim of this book. It claimed that Jesus was human being; it rejects the idea of holy trinity and the crucifixion of Jesus. With this claim, prominently displaying the cross on its pages is self-defeating.

• The research by Scholars on the Muslims history relating to the writing on Koran indicates that no Muslim scholar has ever referred this gospel until after 1500. This was true also concerning Christian scholars. It is argued that why the Muslim scholars did not refer to this Gospel when there was an intense debate going on between the Muslims and Christians about the identity of Jesus between the seventh and 15th century. It has been established that not one scholar mentioned about the existence of this book at that period of time.

• Furthermore, the Christians scholars like Irenaeus wrote extensively against the existence of various other anti Christians documents, such as Gnostic gospels classifying them as heretical. Yet not one of Irreaeus letters or documents mentions the Gospel of Barnabas.

• Perhaps the most indicative of its late date is that the Gospel describes medieval life in Western Europe as well as a 100-year Jubilee that was not declared until fourteenth century.

Not only does the evidence argue against it being written by Barnabas in the first century but also scholars believe the gospel is a forgery. Scholarly research has proved that it was a fake. Even Muslim scholars likewise are also of opinion that it is a fake. The Concise Encyclopaedia of Islam states that ”as regards the ‘Gospel of Barnabas ‘ itself, there is no question that it is a medieval forgery”.
