To ease tensions between Muslims and Christians. I doubt this will help. Maybe we should stop calling Jesus Lord and Son of God, that’s probably more upsetting to the Muslims:

Catholic churches in the Netherlands should use the name Allah for God to ease tensions between Muslims and Christians, says a Dutch bishop.
Tiny Muskens, the bishop of Breda, told the Dutch TV program “Network” Monday night he believes God doesn’t mind what he is called, Radio Netherlands Worldwide reported.
The Almighty is above such “discussion and bickering,” he insisted.
Muskens points to Indonesia, where he served 30 years ago, as an example for Dutch churches. Christians in the Middle East also use the term Allah for God.

“Sure. Lets call God Allah. Lets then call a church a mosque and pray five times a day. Ramadan sounds like fun,” wrote Welmoet Koppenhol.

A Muslim spokesman, for Amsterdam’s union of Moroccan mosques, said Muslims had not asked for such a gesture from Christians, the AP reported.
