Pope Francis has issued the fourth encyclical of his papacy, denouncing a world that “is losing its heart” during times of global turmoil marked by “wars, socio-economic disparities and the uses of technology that threaten our humanity.

In his fourth encyclical, “Dilexit Nos,” Pope Francis calls on believers to rediscover devotion to the Sacred Heart of Jesus and, through it, to love our brothers and sisters in the church and world.

The approximately 30,000-word encyclical draws extensively from Scripture and tradition, featuring insights from St. Thérèse of Lisieux, St. Francis de Sales, and St. Charles de Foucauld.

In an era of artificial intelligence, "we cannot forget that poetry and love are necessary to save our humanity,’’ Pope Francis wrote.
