https://www.blueletterbible.org/faq/don_stewart/don_stewart_192.cfmThe New Testament gives the account of the life of Jesus Christ written by His disciples. The question is often asked about Jesus is, "Why don't we have anything in writing from Him?" Would He have been able to write? If so, then why didn't He leave us with any written record?
Jesus Could Read And WriteThe New Testament informs us that Jesus could both read and write. The Gospel of Luke tells us of an incident where Jesus read from the prophet Isaiah.
From this passage we can see that Jesus had the ability to read. He found the place in the scroll where He wanted to read and read the desired portion.
Jesus Wrote Something On The GroundThere is a passage in John's Gospel that demonstrates Jesus had the ability to write:
The fact that Jesus could write is taught in this passage. We should not assume that He just doodled on the ground. He wrote something that caused the religious leaders to leave the scene. Exactly what He wrote has been the subject of endless speculation. However, no one knows for certain what He wrote.
Although the authenticity of this passage is in dispute, almost everyone agrees that it reflects an actual occurrence in the ministry of Jesus.
Why Didn't He Write Something For Us?If Jesus could read and write, then why didn't' He leave behind anything for humanity? The answer is we simply do not know why Jesus did not write any texts setting down His teachings, or give us any firsthand knowledge of His innermost thoughts. These questions, which have been a puzzle to people since the first century, have no real answer.
Do We Have A Letter From Jesus?There is an ancient letter that purports to have been written from Jesus. It is known as, "The Letter to King Abgar." Abgar was a real king who reigned from A.D. 9 to A.D. 46 in what is in modern- day Turkey. As the story goes, King Abgar wrote first to Jesus requesting a miracle.
The Reply Of Jesus To King AbgarIt is recorded that Jesus replied by means of a courier. He began the letter by a saying that is found in John's gospel.
Jesus, according to His letter, declined Abgar's invitation because He had not fulfilled His ministry. However, Jesus wrote that He would send one of His disciples after His ascension, "so that he may cure your illness and give life to you and to those who are with you."
There Was A Happy EndingThe story had a happy ending according to the fourth century church Father Eusebius. He said that Jesus' disciple Thaddeus went to Abgar and healed him. Eusebius did not doubt that Jesus could write. He also said that in the archives of Edessa he had actually seen the correspondence between the two. It did not seem to bother Him that this writing from Jesus did not find its way into the New Testament.
This Letter Was Copied Many TimesBetween the third and eighth century this purported letter of Jesus was inscribed on stone, papyri, and broken pieces of pottery. The letter was also written on amulets. Obviously many people assumed that it was authentic.
The Authenticity Of The Letter Is DisputedThe letter was not accepted as authentic by all early church authorities. Jerome and Augustine, writing about seventy years after Eusebius, state that Jesus did not leave anything in writing. Though most scholars have reject the story as legendary an explanation has to be given why Eusebius would have argued for its authenticity. There is no apparent motive that he would have had for vouching for the story if he did believe it to be true. Some modern scholars are giving this story a second look. At best we can say that it is not impossible that Jesus could have written this letter.
SummaryJesus had the ability to both read and write. These abilities were demonstrated in the New Testament. In a synagogue in Nazareth He opened the scroll of the prophet Isaiah and read from a chosen part. In the story of the woman taken in adultery we find Jesus writing something on the ground that caused the religious leaders to leave Him and the woman alone.
As to whether He wrote anything, such as the Letter to King Abgar, is in much dispute. All that we can know for certain is that Jesus could have written letters or books if He so wished. Why He did not leave anything for us in writing, whether it be a systematic arrangement of His teachings or His inner thoughts, we simply do not know.
