Good without God?

Good without God is the ambiguous part-title to this interesting editorial article on atheism and religion in the Guardian 15/7/19 (The Guardian view on atheism):

Not sure if they mean it’s good to be without God or you can be good without God or?  There appears to be an implicit sense of concern in the article and I wonder if Quakers, nontheist or otherwise, have the answers?

I note that, for Britain, citing the British Social Attitudes Survey: “Even among the over-75s, only a third identify as Anglican. More than half of British people now say that they have no religion; about two-fifths are Christians of one sort of another; 9% are Muslims.”
