Although the Christian church was split up in 1054 because of differences in opinion between the eastern church and the western church. What we today call the Orthodox Church and the Roman Catholic Church.
The Orthodox typical icons usually depict the Virgin Mary and the infant Jesus, and more rarely, for instance, the crucifixion, which in the western church was much more prevalent.
If you generalize, you could say that the western church is the church of suffering, and the eastern church is the church of happiness.
If you imagine a mental journey from Rome eastward, you feel how you move away from guilt and pain towards joy and light.
