VATICAN CITY  — He called her policies an “attack on God’s plan.” She described him as “medieval.”

But Pope Francis and President Cristina Fernandez de Kirchner, the leader of his native Argentina, kissed and made up Monday _ literally _ at a private meeting at the Vatican.

“Never in my life has a pope kissed me!” Fernandez exclaimed after the encounter, during which she presented the pope with her own token of reconciliation: a mate gourd, which he can use to drink traditional Argentine tea.

Fernandez was the first world leader to meet the new pontiff, who before his elevation last week was known as Jorge Mario Bergoglio, the archbishop of Buenos Aires. Dozens more heads of government and state are due to attend his official installation Tuesday, a ceremony that organizers say could draw as many as 1 million people to the Vatican. Vice President Joe Biden will represent the United States.

Details of what was said between Francis and Fernandez were not released by the Vatican, but Fernandez told reporters that she asked the pope to step into the dispute over the Falkland Islands, which are governed by Britain but also claimed by Argentina. The two countries went to war over the islands in 1982; Argentina lost.

“We want a dialogue, and that’s why we asked the pope to intervene so that the dialogue is successful,” Fernandez said.

There was no word on the pope’s response.

The two have had a tense relationship. As archbishop, Bergoglio attacked the government of Fernandez for not doing enough to help the poor. Bergoglio also opposed legalization of same-sex marriage in Argentina _ the only Latin American country to allow it _ as an offense against God.

Fernandez lashed back by comparing the archbishop to someone out of the Inquisition. She also now skips an annual address by the church in Argentina at which, by tradition, politicians and civic society are exhorted to do better.

Her comments congratulating Francis after his election as pope were seen as tepid. But Fernandez is also aware that her country is predominantly Roman Catholic and that many Argentines are excited about one of their own becoming the leader of the worldwide church.

In advance to Tuesday’s ceremony, the Vatican also announced that Francis has decided to remember his roots by choosing a personal coat of arms that recalls his career as a cleric in Argentina.

Francis opted to keep the same coat of arms that he used as the archbishop of Buenos Aires before his election as the first pope from the New World, but with the addition of the golden papal miter and the crossed keys that unlock the kingdom of God. The shield from his days as archbishop features a logo of the Jesuit order to which he belongs, a golden star symbolizing the Virgin Mary and a flower representing St. Joseph.

The pope’s motto will be “miserando atque eligendo” (Latin for “because he saw him through the eyes of mercy and chose him”), a phrase taken from a homily by the Venerable Bede, an eighth-century English monk, describing Jesus’ call to Matthew to follow him. For Francis, the phrase evokes his own calling to become a priest, which he felt as a 17-year-old, the Vatican said.

The pope also has chosen his personal ring: a band of silver and gold that once belonged to the personal secretary to Pope Paul VI.
