There is one very important point to consider; and this is that in the earlier centuries, outside the circles of initiation, there was not that precision which the present-day teaching of theosophy has given to the doctrine of Reincarnation; this latter, in the mind of the people, became confused with the doctrine of Pre-existence, which affirms that the soul exists before coming into the present body, and will exist in other bodies after leaving this one. This confusion has continued up to the present time, and we find schools of spiritualism in England and America, as well as in other countries, teaching that existence on earth has been preceded and will be followed by a great number of existences on the invisible planes. In reality, this is the doctrine of Rebirths, though there is nothing precise about the teaching. Whether the soul has a single physical body, or takes several in succession, it is none the less continually evolving as it passes into material vehicles, however subtle the matter be; the difference is, therefore, insignificant, unless we wish to enter into details of the process involved, as was the case in the West in the early centuries of Christianity. Did the Fathers of the Church teach Pre-existence? There can be no doubt on this point. In a letter to St. Anastasius, Rufinus said that "this belief was common amongst the early Christian fathers." Arnobius[197] shows his sympathy with this teaching, and adds that St. Clement, of Alexandria, "wrote wonderful accounts of metempsychosis"; and afterwards, in other passages of the same book, he appears to criticise the idea of the plurality of lives. St. Jerome affirms that "the doctrine of transmigration has been secretly taught from ancient times to small numbers of people, as a traditional truth which was not to be divulged."[198] A. Franck quotes this passage on page 184 of his _Kabbale_; Huet, too, gives it in _Origeniana_.[199] The same Father proves himself to be a believer in Pre-existence, in his 94th _Letter to Avitus_, where he agrees with Origen on the subject of the interpretation of a passage from St. Paul,[200] and says that this means "that a divine abode and true repose are to be found in Heaven," and "that there dwell creatures endowed with reason in a state of bliss, before coming down to our visible world, before they fall into the grosser bodies of earth...." Lactantius, whom St. Jerome called the Christian Cicero, though he opposed pagan doctrines, maintained that the soul was capable of immortality and of bodily survival only on the hypothesis that it existed before the body.[201] Nemesius, Bishop of Emissa in Syria, stoutly affirmed the doctrine of Pre-existence, declaring that every Greek who believed in immortality believed also in the pre-existence of the soul. St. Augustine said: "Did I not live in another body, or somewhere else, before entering my mother's womb?"[202]
