Holy Spirit, hidden God: Moral life and the non-believer

The proclamation in I Timothy of God's desire for everyone to be saved and 'reach full knowledge of the truth' had an uneasy passage into the twenty-first century. We are now more 'comfortable' theologically with divine grace and Chrisfs saving action present in other religious traditions and even in the lives of non-believers. Ecumenical and inter-religious dialogue is symptomatic of the former. Yet, can we say the same of the existence of grace, God's self-gift, in the fives of non-believers, especially in its moral dimension? Is it possible to articulate a more integrated account of its presence, particularly in the lives of those who define themselves as non-religious, humanist, agnostic, even atheist?
