A summary of the Encyclical released by the Holy See Press Office explains that in his introduction the Pope recalls how "charity is at the heart of the Church's social doctrine". Yet, given the risk of its being "misinterpreted and detached from ethical living", he warns how "a Christianity of charity without truth would be more or less interchangeable with a pool of good sentiments, helpful for social cohesion, but of little relevance".
The Holy Father makes it clear that development has need of truth. In this context he dwells on two "criteria that govern moral action": justice and the common good. All Christians are called to charity, also by the "institutional path" which affects the life of the "polis", that is, of social coexistence.
