The Gospel of Thomas
These are the secret sayings that the living Jesus spoke and Didymos Judas Thomas recorded.
Logion 1. And he said, "Whoever discovers the interpretation of these sayings will not taste death."
Logion 2. Jesus said, "Those who seek should not stop seeking until they find. When they find, they will be disturbed. When they are disturbed, they will marvel, and will reign over all. [And after they have reigned they will rest.]"
Logion 3: Jesus said, "If your leaders say to you, 'Look, the (Father's) 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 (Father's) kingdom is within you and it is outside you.
When you know yourselves, then you will be known, and you will understand that you are children of the living Father. But if you do not know yourselves, then you live in poverty, and you are the poverty."
Logion 22: Jesus saw some babies nursing. He said to his disciples, "These nursing babies are like those who enter the (Father's) kingdom."
They said to him, "Then shall we enter the (Father's) kingdom as babies?"
Jesus said to them, "When you make the two into one, and when you make the inner like the outer and the outer like the inner, and the upper like the lower, and when you make male and female into a single one, so that the male will not be male nor the female be female, when you make eyes in place of an eye, a hand in place of a hand, a foot in place of a foot, an image in place of an image, then you will enter [the kingdom]."
The Apocalypse of Peter
As the Savior was sitting in the temple in the three hundredth (year) of the covenant and the agreement of the tenth pillar, and being satisfied with the number of the living, incorruptible Majesty, he said to me, "Peter, blessed are those above belonging to the Father, who revealed life to those who are from the life, through me, since I reminded they who are built on what is strong, that they may hear my word, and distinguish words of unrighteousness and transgression of law from righteousness, as being from the height of every word of this Pleroma of truth, having been enlightened in good pleasure by him whom the principalities sought. But they did not find him, nor was he mentioned among any generation of the prophets. He has now appeared among these, in him who appeared, who is the Son of Man, who is exalted above the heavens in a fear of men of like essence. But you yourself, Peter, become perfect in accordance with your name with myself, the one who chose you, because from you I have established a base for the remnant whom I have summoned to knowledge...
Come therefore, let us go on with the completion of the will of the incorruptible Father. For behold,
those who will bring them judgment are coming, and they will put them to shame. But me they cannot touch. And you, O Peter, shall stand in their midst. Do not be afraid because of your cowardice. Their minds shall be closed, for the invisible one has opposed them."
When he had said those things, I saw him seemingly being seized by them. And I said "What do I see, O Lord? That it is you yourself whom they take, and that you are grasping me? Or who is this one, glad and laughing on the tree? And is it another one whose feet and hands they are striking?"
The Savior said to me, "He whom you saw on the tree, glad and laughing, this is the living Jesus. But this one into whose hands and feet they drive the nails is his fleshly part, which is the substitute being put to shame, the one who came into being in his likeness. But look at him and me."
But I, when I had looked, said "Lord, no one is looking at you. Let us flee this place."
But he said to me, "I have told you, 'Leave the blind alone!'. And you, see how they do not know what they are saying. For the son of their glory instead of my servant, they have put to shame."
And I saw someone about to approach us resembling him, even him who was laughing on the tree. And he was <filled> with a Holy Spirit, and he is the Savior. And there was a great, ineffable light around them, and the multitude of ineffable and invisible angels blessing them. And when I looked at him, the one who gives praise was revealed.
And he said to me, "Be strong, for you are the one to whom these mysteries have been given, to know them through revelation, that he whom they crucified is the first-born, and the home of demons, and the stony vessel in which they dwell, of Elohim, of the cross, which is under the Law. But he who stands near him is the living Savior, the first in him, whom they seized and released, who stands joyfully looking at those who did him violence, while they are divided among themselves. Therefore he laughs at their lack of perception, knowing that they are born blind. So then the one susceptible to suffering shall come, since the body is the substitute. But what they released was my incorporeal body. But I am the intellectual Spirit filled with radiant light. He whom you saw coming to me is our intellectual Pleroma, which unites the perfect light with my Holy Spirit."
