The government of Samoa — the Pacific island which is deeply rooted in a history of Christianity and its beliefs — is proposing to "restrict" the practice of other religions that are deemed to promote violence or extremism.

Prime Minister Laaulialemalietoa Leuatea Polataivao Fosi Schmidt has led the chorus for "careful consideration" of a way forward to protect Samoa from incidents which have occurred in Australia and New Zealand/Aotearoa in recent years.

The National Council of Churches has been approached to advise the national government on ideas of the future restriction of non-Christian religions practicing in the country.

"If there are religions that do not believe in our Christian faith, then they should not be accepted here," Mr Schmidt said.

"This is the time to address it."

The parliament in 2017 amended article 1 of the Samoan Constitution to officially list Christianity the state religion, adding "Samoa is a Christian nation founded on God the Father, the Son and the Holy Spirit".

Christianity was first introduced to the Samoan community around 1830 by the London Missionary School, however it remained a secular culture by law for 66 years since its 1961 independence from past colonialism.

The constitution previously described Samoa as "an independent state, based on Christian principles and Samoan custom and traditions".

The recently-elected Prime Minister said the government's stance is to look a century ahead, referencing recent examples in both Australia and Aotearoa, where he deemed "pagan beliefs" have begun to revolt against Christians.

"Will Samoa accept that in the future?" Mr Schmidt said.

"We must consider very carefully, as a nation, the entering of pagan beliefs that are not founded on God.

"Government is advocating measures to restrict non-Christian religions in Samoa."

Nearly 98 per cent of Samoa's population are Christians, made up of 55 per cent of a range of various Protestant faiths. Another 19 per cent are Catholics, 17 per cent aren Mormons, while just 0.4 per cent identify of affiliating with other religions which are not Christian.

Mr Schmidt did acknowledge the current constitution does provide the right to choose a residents' own religion and emphasised that Samoa must consider new laws carefully.

However the Prime Minister, who was only elected the country's new leader in September this year, also pointed out "Christian prayer warriors" were recently attacked by members of a non-Christian religion, stating their rights while quoting their own Gods as a threat.

It was made unclear whether the unconfirmed attack was physical or verbal.

"This is not a decision to be made by government alone - no," he said.

"This is what Samoa must consider as a nation, with the National Council of Churches talking the lead, and advising government."

Mr Schmidt said Samoa must take a consolidated approach to ensure everyone participates in the discussion and decision, suggesting that a national referendum may need to be carried out.

"Are we safe for the next 100 years if we continue like this? Letting other religions and beliefs into the country?" he said.
