History

It is not known who invented the World era and when.

Therefore it was a decision of mere historical convenience, not respecting either faith or morals, which are what is truly of intrinsic value in the Scriptures. Having made this disclaimer, he settles on the Benedictine Chronology of 4963 BC for the purposes of his history.
    • According to the ninth edition of the Encyclopædia Britannica, regarding the so-called Era of the Creation of the World, Des Vignoles asserted in the preface to his Chronologie de l’Histoire Sainte (Chronology of Sacred History, Berlin 1738), that he collected upwards of two-hundred different calculations, the shortest of which reckons only 3483 years between the creation of the world and the commencement of the vulgar era and the longest 6984. The so-called era of the creation of the world is therefore a purely conventional and arbitrary epoch, for which the very nature of the case discussion is hopeless labour.

    Summary

    As the Greek and Roman methods of computing time were connected with certain pagan rites and observances, Christians began at an early period to adopt the Hebrew practice of reckoning their years from the supposed period of the creation of the world.

    Currently the two dominant dates for creation that exist using the Biblical model, are about 5500 BC and about 4000 BC. These are calculated from the genealogies in two versions of the Bible, with most of the difference arising from two versions of Genesis. The older dates of the Church Fathers
