The PNG Government is more concerned with social welfare programs of the churches including health and education.
The main interference in the churches in recent times has been with the gay and lesbian agenda being forced on churches in the National HIV/AIDS campaign from the United Nations and AusAID. The churches were bullied into accepting condoms, contraception, focus on rights without responsibilities.
Same sex marriage and adoption of children was next on the agenda. Same sex marriage required control of the Department for Community Development and the Marriage Committee of clergy.
Failure of churches to toe the line would bring black banning and loss of funding. Now that is interference. Two main churches to suffer was the Catholic church and Salvation Army.
