Pope Francis has ended his inaugural homily with a request to his Christian followers to "pray for me".
He said his role as the Bishop of Rome is to bring hope by service to their faith.
The "authentic power is service" he said, adding that kindness and compassion is "not a sign of weakness".
Pope Francis has promised to bring his followers hope by service at his inauguration in front of a crowd of 150,000 in Rome.
Pope Francis will greet crowds before being inaugurated, a guide to the event at the Vatican today.
