The Lebanese Parliament is the national parliament of the Republic of Lebanon. There are 128 members elected to a four-year term in multi-member constituencies, apportioned among Lebanon's diverse Christian and Muslim denominations but with half of the seats reserved for Christians and half reserved to Muslims per Constitutional Article 24. Lebanon has universal adult suffrage. Its major functions are to elect the President of the republic, to approve the government, and to approve laws and expenditure.

Christianity in Lebanon has a long and continuous history. Biblical Scriptures show that Peter and Paul evangelized the Phoenicians, whom they affiliated to the ancient Patriarchate of Antioch. Christianity spread slowly in Lebanon due to pagans who resisted conversion, but it ultimately spread throughout the country. Even after centuries of Muslim rule, it remains the dominant faith of the Mount Lebanon region and has substantial communities elsewhere.
