(From our correspondents in Sydney) Christianity is announced not only by words but also by the behaviour of those who profess to be believers. This is the core of the three catecheses that mgr. Anders Arborelius, bishop of Stockholm, gave to the young of his country in Sydney. "The personal testimony cannot be left aside states the bishop . Often people who have approached Christianity tell me everything begun when they met believable Christians. And I think in our country the value of the testimony is even stronger". Speaking to SIR during the catecheses, mgr. Arborelius tells of the lights and shadows of Sweden. On one side, he tells, "there are young people with no faith or strength" and "marriage is very weak"; however, on the other side, "there a very high birth rate, one of the highest in Europe", partly the result of some "social policies" that protect women and motherhood.
