The Gospel of Thomas (noncanonical) is Super Funny.

Gnosticism, Early Christianity, and canonical vs noncanoncial gospels

Many people have this misconception that early Christians were unified and a cohesive group, when that could not be further from the truth. Division between Christian groups was just as bad as it is now, as even the very fundementals of the religion were being debated. In this era, there were two main groups of Christians: the proto-orthodox that will later become the Catholic and Orthodox Church, and Gnostic Christians that were deemed heretical and later died out. While there were other smaller denominations back then, but these two were the most prominent. In this era of early Christianity, multiples gospels were being written. First was Mark's in the 70's, then Matthew and Luke's in the 80's, then finally the Gospel of John in the 100's. After these, there were other gospels that were written, but left out of canon for one reason or another. Gospels chosen to be in canon had less to do with whether or not the disciples actually wrote them (they probably didn't), but rather how closely they fit proto-orthodox thought, how well it fit with what was already being passed aruond through word of mouth, and how well it was written. There is a good reason why the noncanonical gospels were not added to the canon, especially the ones with Gnostic thought. Gnostic Christians had a theology so weird and conveluted, that I am going to have to go back and edit this paragraph after reviewing my Early Christian Thought textbook. I'll try to pull out what I do remember, though.

Gnostics believed that other gods existed, but were nowhere near as migthy nor deserving of praise as the Christian God
Gnostics tried to seperate themselves from Judaism by saying the God of the Old Testament was a false one trying to pass off as the "true god" (this is the part I kind of have trouble understanding)
Gnostics believed that the god of the Old Testament and the God of the New Testament were born from a goddess named Sophia. This part also confuses me because if Sophia is the one who birthed these gods, then why isn't she credited as being the true god? I guess because the true god created the Earth and its inhabitants, that he's the true god for us living on here? I'll have to look that one up again.

I go into this dive into Gnostic Christianity because the Gospel of Thomas, while not outritght Valentinian, was clearly made by someone who was a Gnostic Christian. That, and confusing writing along with this one really weird part about women that was misogynistic even back then is why this gospel was not only barred from the canon, but also is super funny.

The Supposed Sayings of Christ:

This "gospel" makes a lot of claims about what Christ said. Here are some of my favorites:

Jesus said to his disciples, "Compare me to someone and tell me whom I am like." Simon Peter said to him, "You are like a righteous angel." Matthew said to him, "You are like a wise philosopher." Thomas said to him, "Master, my mouth is wholly incapable of saying whom you are like." Jesus said, "I am not your master. Because you have drunk, you have become intoxicated from the bubbling spring which I have measured out." And he took him and withdrew and told him three things. When Thomas returned to his companions, they asked him, "What did Jesus say to you?" Thomas said to them, "If I tell you one of the things which he told me, you will pick up stones and throw them at me; a fire will come out of the stones and burn you up."
His 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."
Simon 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."
