From a liberal Augustinian perspective, Christians should affirm several liberal institutions, such as the separation of church and state, religious tolerance, and a number of individual rights. Beyond that, it’s over to the considerations of wisdom. And democracy, best I can tell, remains the best of the worst.
The role of the church during the Lebanese Civil War can serve as a case study of the active role the clergy can play in the Middle East to prevent forced migration of Christians to the West, and preserve their rightful place by resisting at home.
For now, let us cling to liberal democracy as a common grace of God. If God in his providence gave us modernity, let Christians be the stewards who use the freedoms of liberal democracy for the sake of the gospel.
