I am not talking about Christians or indeed, any monotheists perfecting their own personal spiritual lives or their own missions.
I am talking about people of differing viewpoints such as different sects of Christians, Jews, and even Hindus (whose foundation is monotheist and whose scriptures mandate very similar moral absolutes as the Bible) tolerating each others' differing views and seeing what they have in common. Purpose? Not to water down anything, not to promote feelgoodism, but to fight against the rising tide of atheism, forced secularism, homosexualism, godless Marxism and its associated evils.
If this doesn't happen, the dark side - those who hate God by any name - will win, and religious folk can nitpick at each other all the way to the star chamber, the Gulag, or the firing squad.
