Shepherd of Hermas
The Shepherd of Hermas is a Christian text that circulated in the early Christian church. It records a series of visions relayed by a slave named Hermas. Hermas is shown a series of allegorical images representing the Church, and then sees a vision of an angel who appears in the form of a shepherd, and teaches Hermas a system of commandments and ethical teachings. While generally viewed favorably, it was ultimately excluded from the Biblical canon as not having been written by an Apostle.
The Shepherd of Hermas is only seen as canonical by the Ethiopian Orthodox Church.
