Final answer:
True. The claim that everyone loved Bishop Nestorius when he became bishop is an oversimplification and historical evidence points to controversies that led to his condemnation and exile.
Step-by-step explanation:
The statement about Bishop Nestorius being loved by all the people when he became bishop cannot be universally deemed true or false without a specific context. Historical events suggest there were controversies and conflicts surrounding Nestorius's teachings, especially concerning the divine and human natures in Jesus Christ. Nestorius's ideas eventually led to the Nestorian Schism, which resulted in his condemnation and exile. Therefore, the idea that everyone loved Bishop Nestorius is likely an oversimplification of the complex relationship between religious leaders and their congregations or followers at that time.
