Actually, the example that I gave is for Malaysia. For example, a Christian who practice the old testament and of direct descendants can marry a muslim. This is the same for the majority of Islamic country, although some Middle East country may be more strict in this. Indonesia is the odd one out, being the very few Islamic country that adopts a variation to this teachings.Originally Posted by Vixey
How come ulama has the power? Every religion has its "governing body". For example, for the Roman Catholics, they have the Vatican, or The Holy See, which is the governing body of the Roman Catholic Church and the Vatican City headed by the Pope. And the chain goes down, with every country has their own "governing body".
For Islam and the Malaysia, it is the council of ulama's. Most Islamic countries also have their council of ulama's. The practice of Islam in different countries may vary due to the different branches and teachings that they adopt. This is the same for other religions as well.
An interesting case study would be about the ruling of gay Priests in the US and other countries. Some countries allowed it, some dont. All decided by the respective governing body of the religion. You can find out more through google if you want.
