Pope Benedict XVI has issued his second document, also on love. His first was Deus Caritas Est, God is Love. Which was a great reflection on the nature of the Trinity.
This new document is a Post-Synodal Apostolic Exhortation. In other words, it is a summation of a synod of Bishops that came together in 2005 to examine the issues of the Eucharist, the liturgy and liturgical renewal as it is formulated in Vatican II documents. It is titled, Sacramentum Caritatis, which means Sacrament of Love. I haven't read the entire document yet, but will soon.
Do yourself a favor and open this present from the Church.
