Which gospel was written for the gentiles?

John's Gospel was written for what is now called the Johannine community. Luke's gospel also seems to have been written for a limited community, although it may also have been intended to demonstrate to outsiders, such as the Roman authorities, the antiquity and virtues of Christianity. Some believe that Matthew's Gospel was written for a Jewish community, and if so this would have been a diaspora community. Mark's Gospel shows no indication of having been intended for a limited community, and in fact this gospel was known to the authors of all the other New Testament gospels - Matthew, Luke and John. So, Mark was the most universal of the gospels.
