State and Religion relationship in Indonesian Constitution
Unlike in theocratic states, in Indonesia, clerics may issue a verdict (fatwa) but this verdict is not legally binding.
It is important to note that the word "God" appeared many times on the Indonesian constitution. Nevertheless, unlike the UK/Greece model, Indonesian Constitution is silent with regard to recognition of a particular religion.
There is no single article in our Constitution that mentions the name of a particular religion. Article 29 stipulates "the state is based on the belief in the One and Supreme God" but does not explain further -- "God according to who?"
Moreover, although Indonesia "is based in the one and only god", the constitutional practices in the past allowed non-atheistic beliefs (as implemented by the Indonesian Communist Party and local beliefs such as kejawen) to grow.
I therefore tend to conclude the Indonesian model sits somewhere between the German and the Greece/UK model.
The Indonesian Constitution is not neutral towards religion. It is "pro-religion" in the sense that it prefers and supports a theistic worldview rather than the non-theist worldview, but is nevertheless neutral on which theistic view it prefers the most. Thus, the idea of "state-acknowledged religions" (agama yang diakui negara) actually has no constitutional basis.
A pro-religion constitution means that religious adherents may enjoy more freedom of religion in positive terms (the freedom to exercise) through state facilities compared to adherents of non/atheistic beliefs.
However, the negative freedom (the freedom not to be forced toward a particular religion or belief) of all persons remains protected. The power struggle within a particular religion is clearly not the business of the state.
The state has no constitutional authority to dictate its citizens on which version of God it shall worship. Forcing a particular religious interpretation would infringe article 29 (2) of the Constitution.
