As a generalist I tend to think of the big picture and push global conceptions, which can get speculative, but should provide insight in some way. There are many ways of slicing up history that show a pattern, but we crave meaning and so expect patterns. For example, it is helpful to adopt a rather conventional division of history into periods of primeval, ancient, medieval, modern, and post-modern (for lack of a better term). At least this gives us something to start with and modify or clarify later on.
I have written before briefly about the fourfold Church. Here is a division of Christian history and cosmology that corresponds to the fourfold Gospel and the fourfold Church:
Patristic period – ca. first through fifth century, which is championed by the (Eastern) Orthodox Church. Their authoritative writings are the Bible and the seven ecumenical councils. This corresponds to a cosmology of the seven celestial bodies visible to the naked eye (Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn).
Medieval period – ca. fifth through fifteenth centuries, which is championed by the (Roman) Catholic Church. Their authoritative writings are the Bible and that of the Magisterium centered in Rome. This corresponds to a geocentric cosmology in which space and time are absolute.
Modern period – ca. fifteenth through twentieth centuries, which is championed by the churches of the Reformation. Their authoritative writings are the Bible and the various confessions or statements of faith. This corresponds to a heliocentric cosmology in which time is absolute.
Post-modern period – ca. from the twentieth century, which is championed by the Pentecostal and Charismatic churches. Their authoritative writings are the Bible and the writings of the various spirit-led teachers. This corresponds to a relativistic cosmology in which space and time are relative.
When we learn about history, we should learn the importance of the change from a geocentric to a heliocentric cosmology. Changes in cosmology go beyond theories of physics or astronomy. They correspond to spiritual changes as well.
