Today, even as belief in God fades across the West, the countries that were once collectively known as Christendom continue to bear the stamp of the two-millennia-old revolution that Christianity represents. It is the principal reason why, by and large, most of us who live in post-Christian societies still take for granted that it is nobler to suffer than to inflict suffering. It is why we generally assume that every human life is of equal value. In my morals and ethics, I have learned to accept that I am not Greek or Roman at all, but thoroughly and proudly Christian.
I’m a bit late to the party with this one: historian of the classical world Tom Holland on realising that Christianity is the basis of his (and our) moral outlook.
