5.3.6.2 The prohibition against killing in the New Testament

Jesus' interpretation of the Fifth Commandment went far beyond the original meaning: "You have heard that it was said to those of old, 'You shall not murder, and whoever murders will be in danger of the judgement.' But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgement" (Matthew 5: 21-22). Thus He did not confine the observance of this commandment to its literal fulfilment, but also took into account the individual's inner attitude. Accordingly we read as follows in 1 John 3: 15: "Whoever hates his brother is a murderer."
