[4] In 1975, Luzzago joined the Sovereign Military Order of Malta as a Knight of Honour and Devotion in the Grand Priory of Lombardy and Venice.
[4] In 2011, Luzzago was promoted to the rank of Knight Commander of Justice in the Grand Priory of Rome, where he held the position of Delegate of the Northern Marches[5] and head of the library.

[3] He swore his oath before the members of the Council Complete of State and the Pope’s Special Delegate, Cardinal-designate Silvano Maria Tomasi.
[11] In the face of Russian invasion of Ukraine, Luzzago accompanied the Pope at the penitential liturgy in St Peter's Basilica on 25 March of the same year.
