What about Jesus?
St Augustine could also have appealed to how Jesus spoke. His disciples were shocked at how blunt he was:
“Then the disciples came and said to him, ‘Do you know that the Pharisees were offended when they heard this saying?’ (Matthew 15:12)
The disciples were concerned about how he was offending people with his teaching. Jesus, however, was not afraid of offending others. He spoke plainly. He knew that people needed to hear the truth and that for some of them it would lead to their salvation.
