The Catholic Church in Lebanon is particularly complex, given the mix of rite-specific (Latin and Eastern Catholic) branches, yet its entire episcopate is joined in a special Assembly of the Catholic Patriarchs and Bishops of Lebanon.

The Latin pre-diocesan jurisdiction partakes in the Episcopal conference of the Arab region Latin bishops.

Four of the five Eastern Catholic churches (not the Chaldean Catholics) count Lebanese member(s) in their Patriarchal Synods, Antioch/Beirut being thrice a Patriarchal see in name and/or fact :

• Synod of the Maronite Church (mainly Lebanese)
• Synod of the Greek-Melkite Catholic Church
• Synod of the Syriac Catholic Church (each with a major Lebanese component)
• Synod of the Armenian Catholic Church.

There also is an Apostolic Nunciature to Lebanon as papal diplomatic representation (embassy-level), headquartered in Jounieh, but accredited in the national capital Beirut.
