Gospels

Gospel of Matthew:
- written by the apostle of the same name. The style of the book is exactly what would be expected of a man who was once a tax collector. Matthew wrote this book in the early period of the church, probably around A.D. 50. This was a time when most Christians were Jewish converts.Matthew intends to prove to the Jews that Jesus Christ is the promised Messiah.

Gospel of Mark:
- The unanimous testimony of early church fathers that Mark was the author. He was an associate of the Apostle Peter, and evidently his spiritual son. The Gospel of Mark was likely one of the first books written in the New Testament, probably in A.D. 57-59. Mark’s gospel appears to be targeted to the Roman believers.

Gospel of Luke:
- The Gospel of Luke does not identify its author. The Gospel of Luke was likely written between A.D. 58 and 65. This book’s purpose is to reveal the Lord Jesus Christ and all He “began to do and to teach until the day he was taken up to heaven”
Gospel of John:
- describes the author as "the disciple whom Jesus loved," and for both historical and internal reasons this is understood to be John the Apostle. dated around A.D. 135 require the book to have been written, copied, and circulated before then. purpose as follows: "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."
