Christianity and politics cannot and should not be divided. But in times of deep social division, how do Christians make political choices that aim to build a society of justice and peace, where wholeness and unity reign? With special reference to two apparently very different contexts, Brazil and the Czech Republic, this book delves into this question, suggesting that behind a clash of political populisms, there is a deeper theological conflict. Grace, the action of God in the world, is understood by some as material reward for their giving, and thus as an entitlement to goods, financial rewards, or narrow national interests. For others, grace is a gift of God that always goes beyond any attempt to possess it and enables attention to the other, especially the other who is poor, excluded, and oppressed. What this means concretely is discussed through a close reading of Pope Francis's Fratelli Tutti. Another world is possible, and this book sets out a vision of what it will look like.
