Sikhism, Arya Samaj and the
Prajapita Brahmakumaris are also monotheistic religions like the Jehovah's Witnesses, believing in an incorporeal monotheistic God, and which accepts reincarnation as a central belief in their teachings.
In the west, the works of psychiatrists like Dr. Brian Weiss,
Dr.Michael Newton and Dr. Ian Stevenson have also shown that reincarnation may have its basis in reality and maybe a fact afterall.
Just as the Ebionites insisted strictly on a vegetarian diet, the early Christian gnostic sects as well as Origen also taught about the concept of reincarnation.
It is quite possible that reincarnation as a teaching was there in the early christian scriptures which were edited out by the romans in the councils of Nicea and Constantinople as it conflicted with their own ideas and sensibilities about spirituality. St. Jerome had criticized Origen's views on reincarnation in his writings.
