Who are the Theraputae What are their Doctrines and how did it affect the Doctrines of present Christianity if any?

Answer 1

The Therapeutae were described by Philo of Alexandria as philosophers. They were a strict Jewish sect, whose members lived a monastic life in Egypt, but were found elsewhere in the Jewish diaspora. Modern scholars regard them as a branch of the Essenes.

Eusebius regarded the Therapeutae as having been Christians. In fact, he deduced that because Philo expressed admiration for the Therapeutae, he must also have been Christian. Professor Alvar Ellegard (Jesus One Hundred Years Before Christ) sees them as forerunners of Christians.

The little we know about the Therapeutae comes mainly from Philo and Eusebius, but it seems they influenced the development of Christian monastic orders in later centuries.
