Golden Rule is rooted in most religions
Noted British essayist and novelist G.K. Chesterton observed that Christianity had not been tried and found wanting, but was found exceedingly difficult and consequently had been rarely tried.
Chesterton was no doubt referring to the demanding brand of Christianity practiced by St. Francis of Assisi and Mother Theresa that requires the abandonment of self in service to others.
St. Francis and Mother Theresa renounced their worldly inheritance for a life of poverty and service to God and mankind. They both tried Christianity, found it to be difficult, but accepted the challenge anyway.
Religious writer Karen Armstrong argues that the Golden Rule is rooted in many different religious traditions and unites many divergent believers around one central concept. As Christians, Jesus reminds us that how we treat “the least of these” is how we treat Him.
And by the way, judged in the context of His own time, in today’s world would Jesus be considered a liberal or conservative?
