Omnism - every logophiles dream word. Truth isn't just found in christianity, hinduism, buddhism or islam, it can be found in all religions. This is true spirituality. Holy shit, I thought I was the only one!
There are: good Christians and evil Christians, good Muslims and evil Muslims. Alternatively, there are ethical people who live without religion and evil people who live without religion. Religion does not always correlate with ethics. Get over it.
It is not necessary to believe in god to be a good person. in a way, the traditional notion of god is outdated. One can be spiritual but not religious. it is not necessary to go to church and give money - for many, nature can be a church.
