While the communication of the “good news” is primarily oral, by way of apostolic teaching (Mt. 28:18-20), it was natural that the written method of preserving salvation history employed by the Jewish people would also be used by the Church. The Church, for example, utilized the Jewish Scriptures translated into Greek (the Septuagint of Alexandria) for purposes of evangelization, connected the promises of Old Covenant with their fulfilment in the New. Among the Evangelists, St. Luke provides an explanation of his specific purpose, while alluding to others having written their accounts, as well. Luke 1:1-4 Inasmuch as many have undertaken to compile a narrative of the things which have been accomplished among us, just as they were delivered to us by those who from the beginning were eyewitnesses and ministers of the word, it seemed good to me also, having followed all things closely for some time past, to write an orderly account for you, most excellent Theophilus, that you may know the truth concerning the things of which you have been informed. For St. John’s part, he concludes his Gospel with the following statement of his motive, more theological than historical. John 20:30-31 Now Jesus did many other signs in the presence of the disciples, which are not written in this book; but these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name.
