How does the evolution of the christian world in the third-wave era compare with that of tang and song dynasty china and of the islamic world?

The Western Catholic Christian world was less developed in comparison to Tang and Song dynasty China due to smaller cities, weaker political authorities, a fragmented political structure, a less commercialized economy, and inferior technology. It was also a more militarized society.

However, the Orthodox Christian world was more similar to Tang and Song dynasty China because of comparable cities, a powerful emperor, a unified government, a professional bureaucracy, a commercialized economy, and a technologically advanced society.
