Here's Pope Benedict XVI's first encyclical, Deus Caritas Est - God is love.
He writes about the many different kinds of love and, without dismissing Eros, points out that a false conception of sexual love diminshes people and turns them into mere "commodities." He makes many links to the Old Testament and to the role of Israel. He writes about the afflictions of Job and quotes St Augustine's Sermo 52:
"Si comprehendis, non est Deus"
(If you understand him, he is not God.)
He is careful to separate the role of the church from that of politics. He posits that a personal relationship with God excludes participation in terrorism.
