You're thinking the synoptic gospels were narratives lacking the mystic connections, then the Gospel of Thomas would provide the links needed to explain the puzzling narrations?

I might mention an idea I myself believe—that the typically biblical strategy is to create a narrative that leads to an open space. The naive reader typically fills it in with assumptions, as a more wary reader might go back and pause before the absence.

I found this idea expressed by two Bible scholars.

Hugh S. Pyper: ”A key part of the Bible's uncanny power over its readers resides in the silences. These induce the readers to make their own utterances to fill the gap, often with unforeseen consequences."

Jan Joosten: “It is in the nature of biblical narrative to leave gaps and blanks to be filled in by the readers as well as they are able.”
