The Lutheran Church in Papua New Guinea says weak migration laws, the internet and increased contact with the outside world are to blame for an increase in pornography and violence against women.
The Post Courier newspaper reports the head of the church, Bishop Wesley Kigasung, saying laws must be changed to make it hard for anyone to enter the country and do what they like.
In a press conference, Dr Kigasung, says violence against women is on the increase and this is partly due to pornography.
He says it shows that the country's traditional, cultural and Christian ethics and values are breaking down.
Bishop Kigasung says it is important that the family unit is kept strong and issues like incest, rape and violence must be kept out.
He says there is also widespread abuse of alcohol and drugs among young people.
Bishop Kigasung says all churches in PNG and the government at all levels should work together to address these issues.
