Note: Video from 2009. The connection between the early Christians and the Essenes is an interesting one because of the similarities in their teachings:
"The obvious links between the practices at Qumran and those of Jesus’ disciples are well known. They include the Council of Twelve; the communal meal; healing and exorcism; sharing possessions; baptism; antagonism towards the main Jewish sects; looking to the end of the world and the coming of a messiah. Similar imagery recurs: the cornerstone, the spring of living waters, the Many; the Children of Light; the poor; the elect; the meek; the Son of God." Source: The Bible And Interpretation.
John Allegro, the controversial Dead Sea Scrolls scholar, thought that early Christian congregations were actually part of an Essene diaspora out of Israel which followed the Roman destruction of the temple in 70 AD. He described this theory in his book The Dead Sea Scrolls and the Christian Myth, well worth reading if you're interested in the possible origins of the religion. I thought his argument was very plausible, especially because it explains the rapid appearance of Christian congregations in the first century.
