EBT Buddhism (Buddhism of EBTs) or an EBT follower/monk is about early Buddhism based on EBTs.
Earliest use of the English phrase “early Buddhism” to refer to both Pali and Chinese early Buddhist texts is:
Choong Mun-keat. The Notion of Emptiness in Early Buddhism (1995; second revised edition, Motilal Banarsidass, Delhi, 1999). https://discourse.suttacentral.net/t/ea … sm/33436/3
