We can see this idea in some early literature, mainly from gnostic or docetic sources but also at times from orthodox ones as well. The Sethian
Gospel of Judas (ca. late 2nd century), for instance, notes:
When Jesus appeared on earth, he performed signs and great wonders for the salvation of humanity. And since some walked in the path of righteousness while others walked in their transgressions, the twelve disciples were called. He began to speak with them about the otherworldly mysteries beyond the cosmos and what would take place hereafter.
Now often he would not reveal himself to his disciples, but among them you would find him as a child.
The
Acts of John (late 2nd century), in its overtly docetic section, has the following (87-90):
… Now those who were present inquired about the cause, and were especially perplexed because Drusiana has said, “
The Lord appeared to me in the tomb in the form of John and in that of a young man.” So since they were perplexed and in some ways not yet established in the faith, John took it patiently and said,
“Men and brethren, you have experienced nothing strange or incredible in your perception of the , since even we whom he chose to be his apostles have suffered many temptations; and I cannot speak or write to you the things which I have seen and heard. Yet now I must adapt myself to your hearing and according to each man’s capacity I will communicate to you those things whereof you are able to become hearers, that you may see the glory that surrounds him that was and is both now and evermore.
“For when he had chosen Peter and Andrew, who were brothers, he came to me and to my brother James, saying, ‘I need you, come with me!’
And my brother said this to me, ‘John, what does he want, this child on the shore who called us?’ And I said, ‘Which child?’ And he answered me, ‘The one who is beckoning to us.’ And I said, “This is because of the long watch we kept at sea. You are not seeing straight, brother James.
Do you not see the man standing there who is handsome, fair, and cheerful-looking?’ But he said to me, ‘I do not see that man, my brother. But let us go, and we will see what this means.’
“And when we had brought the boat to land we saw how he also helped us to beach the boat. And as we left the place, wishing to follow him,
he appeared to me again as rather bald- but with a thick flowing beard, but to James as a young man whose beard was just beginning. So we wondered both of us about the meaning of the vision we had seen. Then as we both followed him we became gradually perplexed about this matter.
“
But then there appeared to me a yet more amazing sight; I tried to see him as he was, and I never saw his eyes closing, but always open. But he sometimes appeared to me as a small man with no good looks, and then again as looking up to heaven. And he had another strange (property); when I reclined at table he would take me to his own breast, and I held him (fast);
and sometimes his breast felt to me smooth and soft, but sometimes hard like rock, so that I was perplexed in my (mind) and said, ‘Why do I find it so?’ And as I thought about it, he…”
“Another time he took me and James and Peter to the mountain where he used to pray, and we saw him a light such that a man, who uses mortal speech, cannot describe what it was like. Again he took us three likewise up the mountain, saying, ‘Come with me.’ And again we went; and we saw him at a distance praying. Then I, since he loved me, went quietly up to him, as if he could not see, and stood looking at his hinder parts;
and I saw him not dressed in clothes at all, but stripped of those we (usually) saw (upon him), and not like a man at all. (And I saw that) his feet were whiter than snow, so that the ground there was lit up by his feet; and that his head stretched up to heaven, so that I was afraid and cried out; and he, turning about,
appeared as a small man and caught hold of my beard and pulled it and said to me, ‘John, do not be faithless, but believing, and not inquisitive.’ And I said to him, ‘Why, Lord, what have I done?’ But I tell you, my brethren, that I suffered such pain for thirty days in the place where he touched my beard, that I said to him, ‘Lord, if your playful tug has caused such pain, what (would it be) if you had dealt me a blow?’ And he said to me, ‘Let it be your concern from now on not to tempt him that cannot be tempted.’”
