The Apostolic Constitution, Universi Dominici Gregis, released by Blessed Pope John Paul II on 22 February 1996, which regulates the Papal conclave, and as such, was in effect in the 2005 papal conclave, and should also govern the 2013 papal conclave, which will begin within a month or so from now.

Let us pray for the Cardinal-electors, for our Pope Benedict XVI, for his successor-to-be, and for the Universal Church and the world. Amen.
