During the Nov. 18-20 visit, the pope planned to unveil a document he wrote as a follow-up to the 2009 Synod of Bishops on Africa. The text synthesizes the synod's conclusions and presents pastoral priorities for the church in Africa.
The pope said the whole point of the synod was to help make Christians "the salt of the earth and the light of the world."
The pope's schedule in Benin included meetings with political authorities and interreligious representatives, an encounter with children, liturgies with Catholics and a Mass to present the post-synodal document.
The Benin trip is Pope Benedict's second apostolic visit to Africa. He visited Cameroon and Angola in 2009.
