Why do we call the Orthodox churches Churches but not protestant communities?

The term "Church" in Orthodox Christianity signifies a historical and theological continuity rooted in apostolic succession and the sacramental life, emphasizing their connection to early Christianity. In contrast, many Protestant communities emerged as reform movements with varying beliefs about authority, church structure, and sacraments, leading to the use of terms like "community" or "fellowship" to reflect their diverse and often less hierarchical nature. This distinction highlights the Orthodox emphasis on tradition and unity, while Protestantism often embraces a more individualistic and decentralized approach.
