Order pro Merito Melitensi

The Order "pro Merito Melitensi" is the order of merit of the Sovereign Military Order of Malta, established in 1920. It is awarded to recipients who have brought honour to the Sovereign Military Order of Malta, promoted Christian values and for charity as defined by the Roman Catholic Church. Unlike Knights or Dames of the Order of Malta (which is a military order of chivalry), those decorated with the Order "pro Merito Melitensi" are not invested in a religious ceremony, do not swear any oath or make any religious commitment. It may therefore be bestowed upon non-Catholics. Conferees include prominent statesmen, such as Presidents Ronald Reagan, who received it while still in office, and George H.W. Bush. 
The order comprises three ranks, including Commander, now rare in the Order of Malta, and has no nobiliary grades, thus being comparable to numerous orders of merit around the world, including the Papal orders, France's Legion of Honour and Britain's Order of the British Empire.
