In his funeral oration, Vice President Nicolas Maduro said Chavez, who died Tuesday at 58 after a long bout with cancer, was the champion of the oppressed and "redeemer of our poor and those of all the world." Perhaps referring to Chavez's frequent tirades against the United States, Maduro said Chavez wanted "a world without empires, without hegemonies."
"There was never a leader more vilified than Hugo Chavez," Maduro, who was sworn in late Friday as interim president, told those assembled at the Venezuelan Military Academy. "But our commander had inside him the biggest shield against infamy a human being can have: his purity and the love of Christ, which saved him and left him undefeated."
The Rev. Jesse Jackson, addressing the congregation, issued a plea for better binational relations and asked God to "heal the breach between the U.S. and Venezuela" and to "let there be peace between nations."
"Let us forgive, redeem and move on to higher ground," Jackson said. "We are neighbors who share the same hemisphere. We play ball together. We share natural resources and we combat drugs together, share dreams and are bound by culture and environment."
Others in attendance included Uruguayan President Jose Mujica and actor Sean Penn, who has expressed his friendship with Chavez as well as gratitude for financial support of relief efforts Penn directed in Haiti. Argentine President Cristina Fernandez de Kirchner unexpectedly left before the service, citing medical reasons, officials said.
Dudamel, the Venezuelan-born music director of the Los Angeles Philharmonic, traveled to Caracas on an overnight flight after a performance Thursday night.
Maduro took the oath as interim president from National Assembly President Diosdado Cabello, swearing to uphold the constitution and laws of Venezuela in the "name of our Commandante Hugo Chavez." The Friday night ceremony was held in the assembly hall in central Caracas.
Riding a wave of sympathy for Chavez, Maduro is heavily favored to win a special election next month for the presidency.
