'The angels were singing peace on earth,' Bishop Zen says of the first Christmas day, when Jesus Christ was born. Peace is surely also a mission, not only a gift. It has to be cultivated, it must be defended. 'Everybody wants peace, but in these times of wars and terrorist activity, it is the ordinary people who are defenceless.' An enforced peace, Bishop Zen adds, is not peace but a state of violence. He is referring to any 'situation of injustice from which it is very difficult to free oneself'. Spreading the concept of justice involves 'unmasking the unjust oppressors and waking up the consciences', he says. But Bishop Zen cautions against fighting injustice using physical force. 'Sometimes it might be an extreme remedy if you don't have any other way, but it is very dangerous as it can go out of control. 'We [Roman Catholics] prefer a peaceful means to fighting war, and that means talking to people about God's plan for man, what is human dignity in the mind of God, and how each person is precious in His eyes. 'In society, everybody should be respected and have human rights, and these should never be violated. In a civilised society, the minority should not be discriminated against, and the weaker groups deserve more care. Only by doing so can we preserve peace. 'The model of our behaviour in society will always be the family. In a family, everybody cares for the sick, the young, the old and the weak. They surround these people with love and care and patience. 'Unfortunately, in society, there is so much violence against the weak. We Catholics are strongly against abortion, because the unborn life is defenceless. Now, in many places, they promote euthanasia. They say they want to make it lawful to help people to die. 'Surely, if there is a widespread acceptance of euthanasia, many people will feel threatened. What about the old man who is sick or in miserable condition? These people may feel they are not worthwhile, that they are a burden on society. We should never consider any person a burden. 'Then there is the cruel concept of competition. This can be a good thing, if it encourages people to do better, but if competition becomes the main criteria, then it is inhuman. Because not everybody can compete, and while competition produces victory, it also produces defeat. You should never consider a human being as a defeated person, and it is dangerous to take those people who are defeated as failures. No, they are not failures, and that should be considered right from their schooling. 'Parents and teachers should never make a child feel defeated. Children should feel that they are always worthwhile, always the object of love - even if they are last in the class, or the naughtiest child. 'This Christmas, my message is to cultivate justice, and then peace will be the fruit of that justice. 'In Hong Kong, my wish is that people celebrate Christmas in an atmosphere of kindness and joy. I hope they will give some thought to the birth of the Saviour, but even those who don't could try to bring more kindness into their lives by helping to change an unjust situation. 'This is especially needed in times of financial difficulty, when people may tend to care only for themselves. 'There is an old saying that when you share difficulties, the difficulties diminish. When you share joy, the joy will multiply. Let us care for each other, and our problems may be easier.'
