Final answer:
The Kingdom of God in Jesus' teaching is primarily about the spiritual realm and transcends physicality. It focuses on spiritual rebirth, universal salvation, and breaks social barriers, allowing Christianity to spread as a universal faith and impacting both the spiritual and economic aspects of society.
Step-by-step explanation:
In the teachings of Jesus as interpreted by the reformed interpreters, the Kingdom of God is primarily about the spiritual realm and is not necessarily physical. Jesus's message was different from other religious movements because it emphasized the personal and internal aspects of faith over external, religious law or political power. His version of the kingdom was more about a transformation of the heart and the way people lived in relation to God and each other, rather than establishing a physical dominion. Moreover, Jesus focused on the spiritual needs of the common people and social outcasts, emphasizing love and compassion over the rigid social hierarchies of the time.
According to Christian doctrine, Jesus, referred to as 'the Christ' meaning 'the anointed one', offered salvation and a chance for spiritual rebirth, which was a source of hope beyond physical life. This promise of salvation was not limited to a specific social class, making Christianity a universal faith early on, breaking down the social barriers that were rampant in Roman society.
An important aspect to consider is how early Christianity also brought about an economic dimension, as communities thrived on the presence of religious relics and the pilgrims they attracted. This interplay of the economic and spiritual underlines the complex nature of religion in society.
