What is unusual, and unique to the Tanchuma-Yelammedenu literature, is labeling the circumcision a mystery. This labeling did not originate in rabbinic culture.
"(...)the Tanchuma-Yelammedenu literature could have borrowed from Sefer Yetzirah. This is not a rabbinic book in any way; it is a sapiential text written in Hebrew (...)
The book tells about how God created the world using basic units of letters and numbers."
After that our father Abraham had seen and pondered over, investigated and understood these things, he designed, engraved and composed them, and received them into his hands
