Personally, I think it's important in some ways. It's important because we need to know and acknowledge the Creator. However, what I'm not agreeing with the wrong teachings of other religion, and their conflict with other religion results to chaos.

It's not so important for me to go to church, what matters to me is doing good things for other people in your own little ways. Loving other people is also loving the Creator, whoever He is. Going to church is non-sense if your attitude is trash.
