Traditionally the Saturday of the Seventh Week marks the morning of a procession to the Chruch of Lazarus in Bethany.  This is the sight of the raising of Lazarus.  Along the way, there is a momentary stop at the spot where Jesus met Mary, the sister of Lazarus.  Once the procession reaches the Lazarium (see:  www.sacred-destinations.com/israel/jerusalem-bethany.htm ) there commences a reading of John 11:45 and various hymns written about Lazarus.  The next morning, the eucharist is administered, followed by batizands reciting the Cyril creed from memory.  They are told that they are still only "hearers".  It is not until they are baptized that the knowledge transforms to understanding of the "higher mystery".  This is the "misteri altioris".  

There are in operation today a number of Grand Priories of Military & Hospitaller Orders of St Lazarus.  They come under various protections of Primates & Sovereigns, some aligned to specific churches and others ecumenical in nature.  Some have a knighting ceremony similar in nature to the Knights of Malta, while still at least one in existence preserves the misteri altioris.

Here is the tomb of St Lazarus and the courtyard of the castle reserved for the Order of Lazarus in Malta...
