It is likely that all the gospels were written to early Christians.
Mark's Gospel was the first of the gospels, written around 70 CE. It appears to have been written to believers, although a secondary audience might have been the Romans who were suspicious of the new religion and who could have been pacified by being shown that Christians were actually Jews who also followed a holy man.
Matthew's Gospel is often said to have been written to the Jews, but modern Jews say that errors in the Gospel would have quickly been detected by any Jews, and they do not believe that it could have been written for Jews. At most it was written for Jews of the diaspora and, if so, more likely for Jewish Christians. The author was at pains to demonstrate the antiquity of Christianity, by frequent references to the Old Testament, but this is more likely to have been defensive than to appeal to pious Jews.
Luke's Gospel is addressed to an unknown patron, Theophilus. Some theologians see Theophilus as a symbolic name, representing all Christians. Whether or not there was a real Theophilus, few seem him as the primary audience for Luke. It was more likely written to members of a community that was already using a copy of Mark's Gospel and were therefore Christians. The author was at pains to demonstrate the historicity of Jesus so, like Matthew, this Gospel might have had as a secondary audience those who scoffed at the new religion.
John's Gospel is widely considered to have been written to a local Christian community now known as the Johannine community. This may well have been a community of Gnostic Christians.
"Gospel" means "The good news"
They were put in the order that was believed to be chronological by early Christians. It is more modern scholarship which has determined that Mark was written first.
There are a number of things that the early Christians did. Some of the common ones include preaching the gospel, meeting for fellowship, sharing bread and so much more.
A:Since the Gospel of Mark was originally anonymous, we do not really know where it was written or why. A common tradition is that it was written in Rome, but as it was written in Greek Koine it is more likely to have been written somewhere in the ancient Near East, where Greek Koine was spoken. We do know that Mark's Gospel was written approximately 70 CE, at the end of the First Roman-Jewish War, so it is very likely that the reason for the gospel had something to do with that war. It may be that the early Christians were keen to show the Romans that their beliefs were not opposed to the Roman peace. It could also be that because the destruction of the Jerusalem Temple and the end of the influence of the Sadducees and Pharisees left the Jews without theological leadership, the early Christians wanted a gospel that showed Christianity to be the natural successor to the old order.
A:John's Gospel was loosely based on Luke's Gospel, which was in turn based on Mark's Gospel, while there are good grounds for believing that Matthew, also based on Mark, was written some time before Luke. Thus, John was the last New Testament gospel to be written, and is dated to the early decades of the second century.
Epistles are letters written to encourage the early Christians. These were encouraging letters to new believers as they started their new journey in Christ.
some of the early Christians seem to have believed that there was a 'Secret Gospel of Mark', but if there ever was such a book, no copy of it survives to the present day. From what we know of the early Gnostic Christians, it is certainly possible that there was another gospel that tells us of the mysteries that initiates in the Marcan community really believed, with the present gospel being the introductory text provided to novices, however this must remain conjecture.

Many think Mark's Gospel was written very early, possibly before all the others.
Christians aim at stopping unsaved people from going to hell by spreading the Gospel (Jesus' death on the cross for our sins).
