Gospel is the standard term for the first four books of the New Testament, describing the life, death, and resurrection of Jesus of Nazareth , although it has a wider meaning taking in both the Christian message (the meaning in the Pauline epistles ) and works centered on that message which may not necessarily touch on the life of Jesus (the Gospel of Thomas , for example, consists entirely of sayings). 
Christianity places a high value on the four canonical gospels, which it considers to be revelations from God and central to its belief system.  Christianity traditionally teaches that the four canonical gospels are an accurate and authoritative representation of the life of Jesus,  but many scholars and historians, as well as some Christians, believe that much of that which is contained in the gospels is not historically reliable. 
The baptism of Jesus and the crucifixion of Jesus are events almost universally agreed upon by biblical scholars to be historically authentic.    Elements whose historical authenticity is disputed include the two accounts of the nativity of Jesus , as well as certain details about the crucifixion and the resurrection.
