Al-Rahi earlier met with Saudi King Salman on the second day of his first visit to Saudi Arabia.
He also held talks with Saad Al-Hariri, who announced his resignation as prime minister of Lebanon from Riyadh on Nov. 4.
Al-Rahi said Hariri will return home as soon as possible and that he supports Hariri’s reasons for resigning, according to media reports.
Hariri announced his resignation in a television broadcast, saying he believed there was an assassination plot against him and accused Hezbollah of sowing strife in the Arab world.
Lebanese Ambassador to Saudi Arabia, Abdul Sattar Issa, said the patriarch’s visit demonstrated the important steps taken by Saudi Arabia to modernize its institutions and to reinforce perceptions of Islam as a religion of moderation.
