Adelophagi (from the Greek terms ἄδηλος adelos "secretly," and φάγω phago "I eat") were a Christian sect mentioned by the anonymous author known as Praedestinatus. They believed that a Christian ought to eat only in private.
The sect's beliefs were based on references to the Old Testament:
It is unclear whether they ate entirely in private, or simply refrained from eating in the presence of members of other sects.
Philastrius suggests that they also rejected the divinity of the Holy Ghost. They seem to have flourished in the latter part of the fourth century, circa 350 AD.[1]
