Excellent point, Krish!

Social Justice is a good Idea and will help. Religion is very complex and will take a combination of approaches to make a difference. I think education is one of them.

I agree that religion is used as a crutch for the poor. But it is also used by financially secure people to feel safe existentially.... free ticket to heaven. And step right up and have God cure your disease, get your child off drugs, whatever...
And religion is used to justify the greed and/or ignorance of people of all income levels that would turn their back on the problem of climate change. Many of them say not to worry about it....God will take take of it for us. EEEEEK !!!

I think new social doctrines will just arise from how we evolve as a culture.
Not many Americans have to question the fact of Greek gods... or Pagan practices.

Working on helping the oppressed is a great first start.

what we should and could do are worlds apart from what we will do.

Social justice, economic stability, free education, and economic equilibrium would all be useful to serve that purpose.

Concrete boons always trump the empty promises of religion.
