Lumen Fidei (Light of Faith) Encyclical Letter seeks to recover the luminous character of faith, which is built into the human being and helps one distinguish the good from the bad, especially today, a time in which the faith is like a light illusory that prevents man go in search of knowledge and restricts their freedom.
This encyclical, begun by Pope Benedict XVI and completed by Pope Francis, concludes the trilogy of letters on the three theological virtues begun by Pope Benedict with Deus Caritas Est on Love and Spe Salvi on hope.
