Final answer:
The Church in the West and East developed differently due to linguistic and cultural differences. The West operated in Latin, required celibate clergy, and elevated the pope's authority, while the East used Greek, allowed married priests, and considered other patriarchs equally authoritative.
Step-by-step explanation:
The development of the Church in the Western and Eastern regions had significant differences. In the West, the Church operated in Latin, the clergy had to be celibate, and the pope was considered the final authority. On the other hand, the Church in the East used Greek, allowed priests to marry, and considered other patriarchs as equally authoritative as the pope. These linguistic and cultural differences contributed to the division between the two regions.
