Abstract: Is it possible to be consistent in holding both that ‘faith should influence politics,’ and that ‘the secular domain of the political should be free from religious interference’? This paper is addressed to people of religious faith who ask how it is possible that they remain faithful to their own religious tradition and yet endorse the claims of a secular political order. Various models are surveyed with which the attempt is made to combine the two perspectives while respecting the distinctiveness of each. One such model proposed by St. Augustine, the coiner of the term ‘secular,’ relies on his distinction of the two cities, the City of God, and the Earthly City. Brian T. Trainor’s more nuanced interpretation of Augustine shows how a religious accommodation of the secular is enabled by the distinction between the secular domain as oriented to and open to the sacred, and the secular domain when it is opposed to and turned away from the sacred. This proposal is explored for its usefulness, for Muslims as well as Christians, in accepting the positive aspects of autonomous secularity without having to endorse the aspects contrary to a faith commitment.
