Editing Humanae vitae (section)

===Pope Benedict XVI===
On 12 May 2008, [[Benedict XVI]] accepted an invitation to talk to participants in the International Congress organized by the [[Pontifical Lateran University]] on the 40th anniversary of {{lang|la|Humanae vitae}}. He put the encyclical in the broader view of love in a global context, a topic he called "so controversial, yet so crucial for humanity's future." {{lang|la|Humanae vitae}} became "a [[sign of contradiction]] but also of continuity of the Church's doctrine and tradition... What was true yesterday is true also today."<ref>Benedict XVI, international congress organized by the Pontifical Lateran University on the 40th anniversary of the encyclical ''Humanae vitae'', 12 May 2008</ref> The Church continues to reflect "in an ever new and deeper way on the fundamental principles that concern marriage and procreation." The key message of {{lang|la|Humanae vitae}} is love. Benedict states, that the fullness of a person is achieved by a unity of soul and body, but neither spirit nor body alone can love, only the two together. If this unity is broken, if only the body is satisfied, love becomes a commodity.<ref>''Deus Caritas Est,'' no. 11</ref>
