The aim of this article is to reflect on the nature of the structural sins in the present times and to offer light on the structural virtues that are in urgent demand for sustainable development of persons and peoples. Our analysis begins in Benedict XVI's Caritas in Veritate. In the encyclical, the pope analyses oversimplification of the human reality by ideologies. The simultaneity of moral underdevelopment and a consumeristic super-development, epistemological gulf between faith and reason, erosion of social capital with the shifting of religion to the private sphere, and the collapse of the human ecology beneath the deterioration of environmental ecology are some of the social sins that Benedict XVI points out in the encyclical. Towards the end of the first section, we attempt to show how Benedict XVI understands that these social sins are also the sins of persons and how the personal is derived into the social. In the second section, we try to develop on the proposals for the structural virtues in Laudato Si'. The starting point is Pope Francis' vision of integral ecology, which is in continuity with Benedict XVI's finding that human ecology and environmental ecology are interconnected. After a brief analysis of Pope Francis' thoughts about the current situation of epistemology, we try to understand the dimensions of the common good, law, and personalism in Laudato Si', from which we can derive threads for the structural virtues.
