When Francis Xavier arrived in Satsuma he began to explain the tenets of his faith to the local Dayamo through an interpreter. The lord, upon understanding the outline of the Christian doctrine presented, nodded and stated that he was familiar with the faith; as his brother had taken vows at a local monastery and when he came to visit he spoke at length on his religion.
(something about the tone made it clear how great the length was)
The Lord of Satsuma then instructed Francis to speak to the local bishop if he wished to preach or establish any religious houses.
