Homosexual Catholic in Indonesia can get married now

What law is there in Indonesia for same sex marriage at the churches?

There is not much information about it. That would be depending on the bravery of churches, that is the priests are to perform the same sex marriage ceremony in the churches.

Pope said it could be do so, if the Catholic churches in Indonesia do not abide the saying of Pope Francis, will God punish these leaders ? Let us see how many of them would suffer the karma.

According to the information in Wikipedia here :

Currently, unlike its neighbouring Commonwealth country, Malaysia, Indonesia does not explicitly have a sodomy law. The national Criminal Code does not prohibit non-commercial, private and consensual sexual activity between two consenting adults of the same-sex. A national bill seeking to criminalize same-sex sexual activity, along with cohabitation, adultery and the practice of witchcraft, failed to be enacted in 2003 and no subsequent bill has been reintroduced.^[19]

Now the marriage ceremony in churches does not have the legal effect thus, this would not be against the law in Indonesia, isn't it ?

So, now you can also look at the gay fingers of the priests in churches. You know whom you can approach.
