essenes and mandaeans and comparision between their doctorine and rituals

essenes are a sect of jewish that dwelled in palestine and syria and have been known as ascetics in jew history in second century (bc).this sect because of their special doctorine and rituals that is different of other jewish sects are accounted as heralds of christianity.all of information about this sect has been drived from greek sources and qumran documents that it´s possible these documents are related to essene school.the basis of  ideas of this sect are based on observance of moral doctorine and the basis of their rituals are on purge and worship.although the theological doctorine of this group is similar to other monastic doctorine but their special theoretical and practical doctorine isolate it from the other schools.since some of these doctorine and rituals are section of theology of mandaean school that continue to live in regions of iran and iraq it has made supposition of relation between them for some scholars.of course on one hand because of the mandaean doctorine has been drived from different religions and also dispersal of their theological doctorine and on the other hand because of some basic different that exists between their doctorine and essense, the possibility of relation between these two groups is a hypothesis that has been represented by a few scholars.anyway the supposition of relation essenes and mandaeans caused to do         comparision between their doctorine and rituals.
