Spe salvi

Pope Benedict XVI has just published the second encyclical of his pontificate, Spe salvi, "on christian hope." His first encyclical, Deus Caritas est, "on christian love," was published two years ago. One assumes that his next encyclical will come out in another two years and will be subtitled "on christian faith," to complete what appears to be a series on the three so-called theological virtues.
