What led to the decline of church simplicity throughout history?

The decline of church simplicity can be traced through various historical developments that led to the establishment of institutionalism and hierarchical structures. Initially, the early church thrived without elaborate rituals and organization; however, over time and particularly after the conversion of Constantine, the church began to mirror the political and social structures of the Roman Empire. This resulted in the establishment of clergy as a privileged class, moving away from the apostolic model where every believer was active in ministry. As such, traditions and ceremonies began to overshadow the simplicity and spiritual vitality that had characterized the church's early years.
