Sayings of Jesus from The Gospel of Thomas

20. The disciples said to Jesus, "Tell us what Heaven's kingdom is like." He said to them, "It's like a mustard seed, the smallest of all seeds, but when it falls on prepared soil, it produces a large plant and becomes a shelter for birds of the sky."

37. His disciples said, "When will you appear to us, and when will we see you?" Jesus said, "When you strip without being ashamed, and you take your clothes and put them under your feet like little children and trample then, then [you] will see the son of the living one and you will not be afraid."

77. Jesus said, "I am the light that is over all things. I am all: from me all came forth, and to me all attained. Split a piece of wood; I am there. Lift up the stone, and you will find me there."

- Gospel of Thomas, verses [20, 37, 77], Nag Hammadi Library

The Gospel of Thomas is a collection of sayings attributed to Jesus of Nazareth and is now accepted by theologians and historians as a true part of the early Christian Church and as one of the most significant manuscripts ever found about Jesus and the history of the Church. Portions of three Greek copies of the Gospel of Thomas were found in Oxyrhynchus, Egypt about one hundred years ago. They are known as Oxyrhynchus Papyrus and were probably written during the early part of the 3rd Century, A complete version in Coptic, the native Egyptian language written in an alphabet derived from the Greek alphabet, was found in Nag Hammadi, Egypt in 1945. That version can be dated to about 340 AD. The Coptic version is a translation of the Greek version. Most scholars believe that the Gospel of Thomas was originally written in Syria in Greek. This Gospel was excluded from the original New Testament after the Conference of Nicea because it puts forward a version of Jesus' teachings that were contrary to ideas popular in the Roman Empire at that time and the later Roman Catholic Church. The heretic idea it professed was that the Kingdom of God is spread out upon the earth now, if people can just come to see it; and that there is divine light within all people, a light that can enable them to see the Kingdom of God upon the earth. This meant that every one of us has the ability to experience God. This philosophy of direct knowledge became known as Gnosticism.
