What are the key differences between Western Christianity and Eastern Christianity?

Western Christianity and Eastern Christianity differ in their theological beliefs, practices, and church structures. Western Christianity, represented by the Roman Catholic Church and Protestant denominations, emphasizes the authority of the Pope, original sin, and the concept of purgatory. Eastern Christianity, represented by the Eastern Orthodox Church, focuses on the authority of councils, theosis (the process of becoming more like God), and the belief in the divine liturgy. Additionally, Western Christianity tends to use more individualistic language and focuses on personal salvation, while Eastern Christianity emphasizes communal salvation and the importance of the church community.
