Pope Frances addressed the fuller meaning on the 10th Commandment, Do not kill at his General Audience recently.
From Vatican News:
Pope Francis said that, read in the context of St John’s Gospel, “Jesus reveals a deeper meaning of this commandment”. Even anger against a sister or brother “is a form of murder”. But Jesus does not stop at this, continued the Pope: in the same logic, Jesus adds that even insult and contempt can kill.
Indifference kills
The Pope continued to provide concrete examples, pointing out how we all possess a sensitive, hidden self that is no less important than our physical self. An “inappropriate phrase”, he said, is enough “to offend the innocence of a child. To hurt a woman, a gesture of coldness is enough. To break a young person’s heart, it is enough to deny them confidence. To annihilate someone, it is enough to ignore them.” Indifference kills, concluded Pope Francis. “Not loving is the first step to killing; and not killing is the first step to loving”.
Antidotes to killing
“Human life needs love”, said the Pope.
“None of us can survive without mercy, we all need forgiveness”, he continued. “So, if killing means destroying, suppressing, eliminating someone, then not killing means taking care of, giving value to, including. And forgiving”.
The Commandment, “Do not kill”, is a call to love and mercy, said Pope Francis. “It is a call to live according to the Lord Jesus”.
