I enjoy reading the Gospel of Thomas and do not think it a true Gospel, according to general definition. It would seem that Christians are quite biased and should not be doing the defining too.

The Nazarene Gospel Restored explains and reveals several major editing events around the Nicene Council and in light of Pragmatism, my interpretation of the Gospel of Mark the other four Gospels of the Bible were following suit, to protect the survived King Jesus while he hovered over the Jerusalem throne in Damascus.

I imagine that the link, based in the preconceived definition about "Gospel" is like studying James CAMERON's The Lost Tomb of Jesus without actually reading it.

So that is what I suggest. Read it for yourselves. I call the Gospel of Thomas - "Slogans of Jesus". I think it quite more inspired than the Book of Mark as it only conveys the trusting and joyful aspects of Jesus' ministry without the commercial basis of integrating Paul's Benjamin heritage of sacrifice.
