Final answer:
Christianity differed from Roman religion by emphasizing belief in God, disapproving of animal sacrifices, and eventually becoming the official state religion of Rome.
Step-by-step explanation:
Christianity differed from the traditional Roman religious belief in many gods/goddesses in several ways. Firstly, Christianity emphasized belief and a personal relationship with God, rather than the veneration of multiple deities. Secondly, Christians disapproved of animal sacrifices and worship of the emperor, and instead focused on prayer and participation in communal worship. Lastly, the spread of Christianity and its acceptance by emperors eventually led to it becoming the official state religion of Rome, resulting in a decline of other cults and religions.
