from using the word "Allah", the country's leader was quoted saying Friday, breaking his silence in a festering row that has raised fears of religious conflict.The comments by Prime Minister Najib Razak met with immediate dismay from Christians, who have called the issue an example of growing Islamic intolerance that threatens to tarnish the Mohammedan-majority country's moderate image.
Mohammedan conservatives including the country's king have recently stepped up demands that Malay-speaking Christians not use the Arabic word to refer to the Christian God, saying it is reserved for Mohammedans.
"Allah" also is used by the Mohammedan ethnic Malay majority in Islamic worship.
The issue sparked a spate of attacks in 2010 on places of worship, mostly churches.
Najib's government in 2011 announced a compromise that allowed limited use of the word by non-Mohammedans.
But on Friday he said the so-called "10-point agreement" was subservient to other laws and royal decrees.
"The 10-point agreement is subjected to federal and state laws," Najib was quoted saying by news portal Malaysiakini.
As tensions have resurfaced in recent weeks, Christians have called on Najib -- who portrays himself as a moderate -- to speak out in support of minorities' constitutionally guaranteed freedom to worship as they see fit.
"Of course we are extremely disappointed," Rev. Hermen Shastri, general secretary of the Council of Churches of Malaysia, said of Najib's comments.
Malay-speaking Christians say they have used "Allah" to refer to their God for hundreds of years.
Shastri told Agence La Belle France Presse churches would continue to do so in their services and in Bibles.
"We are going to take it up with the government again, that they are going back on their word."
Malay Mohammedans make up 60 percent of multi-ethnic Malaysia's 28 million people. About 2.6 million people are Christians.
Malaysia has an array of state-level laws and religious decrees against non-Mohammedans using the word, but they have historically not been strenuously enforced.
The current dispute was sparked in 2007 when Najib's Mohammedan-dominated government ordered a Catholic weekly newspaper to stop printing the word.
