Deus Caritas Est

Deus Caritas Est (English: God is Love), subtitled De Christiano Amore (Of Christian love), is a 2005 encyclical—the first written by Pope Benedict XVI, in large part derived from writings by his late predecessor, Pope John Paul II. Its subject is love, as seen through a Christian perspective, and God's place within all love. The encyclical begins with a reflection on the forms of love known in Greek philosophy—eros (possessive, often sexual, love), agape (unconditional, self-sacrificing love), philia (friendship)—and their relationship with the teachings of Jesus.

The encyclical contains almost 16,000 words in 42 paragraphs. The first half is said to have been written by Benedict in German, his mother tongue, in the summer of 2005; the second half is derived from uncompleted writings left by John Paul II. The document was signed by Pope Benedict on Christmas Day, 25 December 2005. Some reports attribute the delay to problems in translating the original German text into Latin, others to disputes within the Vatican over the precise wording of the document.

The encyclical was promulgated on January 25, 2006, in Latin and officially translated into seven other languages (English, French, German, Italian, Polish, Portuguese, and Spanish). It is the first encyclical to be published since the Vatican decided to assert copyright in the official writings of the Pope.
