Final answer:
It is true that the authority and sequence of the four gospels were established early in the history of Christianity, despite the existence of many other statements about Jesus.
Step-by-step explanation:
The statement that the authority and sequence of the four gospels were established early is true. The four gospels, Matthew, Mark, Luke, and John, serve as the primary sources of information on the life and teachings of Jesus of Nazareth. Although there were many other writings and teachings about Jesus, the four gospels were accepted as authoritative early on in the history of Christianity.
By the end of the first century, these texts had come to be widely used and esteemed within the early Christian communities. While there were diverse interpretations and many debates about Christian doctrine that continued well past this point, the gospels themselves had achieved a special status and formed the core of the New Testament canon.
