Answer - C - Early Christianity shared the idea of personal salvation with Mahayana Buddhism.
Key Takeaway: Also known as the “greater vehicle,” Mahayana Buddhism puts particular emphasis on the idea of personal salvation being accessible to all followers. Though very different from Mahayana Buddhism in its beliefs, early Christianity shared this personal sense of salvation. In early Mahayana Buddhism, salvation could be based upon faith, imaging, or sometimes even invoking Buddha’s name.
Both traditions emphasize the importance of following a spiritual path to achieve liberation from suffering and attain a state of enlightenment. Christianity teaches that salvation is achieved through faith in Jesus Christ and obedience to God's will, while Buddhism teaches that enlightenment is achieved through the practice of the Eightfold Path.
