The word 'Gnosticism" is from Ancient Greek language. It is a collection of religious ideas and systems which originated in the first century AD among early Christian and Jewish sects. These various groups emphasised personal spiritual knowledge more than the teachings, traditions, and authority of the church.
It says that humans are divine souls trapped in the ordinary physical (or material) world. They say that the world was made by an imperfect spirit. Gnostics were dualists and worshipped two (or more) gods; Christians were monists and worshipped one God. Gnostics focused on eradication of ignorance; Christian concern was the eradication of sin.
The Gnostic Gospels: The 52 texts discovered in Nag Hammadi, Egypt include 'secret' gospels poems and myths attributing to Jesus sayings and beliefs which are very different from the New Testament. Gnostic Gospels rejected this idea of the kingdom of God at work on Earth in Jesus.
Three Gnostic gospels - gospel of Thomas, gospel of Philips, gospel of Mary Magdala and gospel of Judas - and some of their contents would bediscussed here. Of these the first one is composed of 114 sayings attributed to Jesus. Almost two thirds of these sayings resemble those found in the canonical gospels. (Numbers in bold fonts are such sayings.) It is one that was found almost full and complete.
INFANCY GOSPEL OF THOMAS

These are the secret sayings which the living Jesus spoke and which Didymos Judas Thomas wrote down.
(2) Jesus said, "Let him who seeks continue seeking until he finds. When he finds, he will become troubled. When he becomes troubled, he will be astonished, and he will rule over the All."
(3) Jesus said, "If those who lead you say to you, 'See, the kingdom is in the sky,' then the birds of the sky will precede you. If they say to you, 'It is in the sea,' then the fish will precede you. Rather, the kingdom is inside of you, and it is outside of you.
(9) Jesus said, "Now the sower went out, took a handful (of seeds), and scattered them. Some fell on the road; the birds came and gathered them up. Others fell on the rock, did not take root in the soil, and did not produce ears. And others fell on thorns; they choked the seed(s) and worms ate them. And others fell on the good soil and it produced good fruit: it bore sixty per measure and a hundred and twenty per measure."
(16) Jesus said, "Men think, perhaps, that it is peace which I have come to cast upon the world. They do not know that it is dissension which I have come to cast upon the earth: fire, sword, and war. For there will be five in a house: three will be against two, and two against three, the father against the son, and the son against the father. And they will stand solitary."
disciples said to Jesus, "Tell us what the kingdom of heaven is like."
He said to them, "It is like a mustard seed. It is the smallest of all seeds. But when it falls on tilled soil, it produces a great plant and becomes a shelter for birds of the sky."
(26) Jesus said, "You see the mote in your brother's eye, but you do not see the beam in your own eye. When you cast the beam out of your own eye, then you will see clearly to cast the mote from your brother's eye."
(33) Jesus said, "Preach from your housetops that which you will hear in your ear. For no one lights a lamp and puts it under a bushel, nor does he put it in a hidden place, but rather he sets it on a lampstand so that everyone who enters and leaves will see its light."
(44) Jesus said, "Whoever blasphemes against the father will be forgiven, and whoever blasphemes against the son will be forgiven, but whoever blasphemes against the holy spirit will not be forgiven either on earth or in heaven." WHY?
(47) Jesus said, "It is impossible for a man to mount two horses or to stretch two bows. And it is impossible for a servant to serve two masters; otherwise, he will honor the one and treat the other contemptuously. No man drinks old wine and immediately desires to drink new wine. And new wine is not put into old wineskins, lest they burst; nor is old wine put into a new wineskin, lest it spoil it. An old patch is not sewn onto a new garment, because a tear would result."
disciples said to him, "Is circumcision beneficial or not?"
He said to them, "If it were beneficial, their father would beget them already circumcised from their mother. Rather, the true circumcision in spirit has become completely profitable."
(54) Jesus said, "Blessed are the poor, for yours is the kingdom of heaven."
(66) Jesus said, "Show me the stone which the builders have rejected. That one is the cornerstone."
(93) <Jesus said,> "Do not give what is holy to dogs, lest they throw them on the dung-heap. Do not throw the pearls to swine, lest they [...] it [...]."
(94) Jesus said, "He who seeks will find, and he who knocks will be let in."
(100) They showed Jesus a gold coin and said to him,
"Caesar's men demand taxes from us."
He said to them, "Give Caesar what belongs to Caesar, give God what belongs to God, and give me what is mine."
(107) Jesus said, "The kingdom is like a shepherd who had a hundred sheep. One of them, the largest, went astray. He left the ninety-nine sheep and looked for that one until he found it. When he had gone to such trouble, he said to the sheep, 'I care for you more than the ninety-nine.'"
Peter said to him, "Let Mary leave us, for women are not worthy of life."
Jesus said, "I myself shall lead her in order to make her male, so that she too may become a living spirit resembling you males. For every woman who will make herself male will enter the kingdom of heaven."
