Gerlach in Houthem, pilgrims from Sint Oedenrode and Hasselt, members of the Armenian, Philippine and Antillian communities in Maastricht, as well as children of primary schools in Maastricht. Furthermore, prayer services, Liturgies of the Hours, lectures and other spiritual activities are organised, some of which take place in the crypt, the Keizerzaal, or other unusual locations. Throughout the 11-day pilgrimage there are priests available for confession or personal counsel. Displaying of the relics The ceremonies of the displaying of the relics in the two main churches constitute the spiritual highlight of the pilgrimage and refer – more so than the processions or other activities – to its medieval origin.

While groups of carriers walk up the central aisle toward the choir stairs, the Litany of the Saints is sung. The carriers position themselves in a semicircle in the chancel area in front of the ambulatory. The service starts with a reading from the Gospel, after which the priest announces the relics with the medieval formula "Thou shall be shown..." The relics are shown in five groups. Each time a group has been announced the carriers step forward near the edge of the choir steps, then lifting up the reliquaries for a few seconds, so they can be seen by all. At no point are the relics taken out of their containers. A prayer is said and the carriers return to their position in the semicircle, after which the next group of relics is announced. In 2018 the order of showing was: relics of Christian martyrs: the reliquary of the apostle Peter, the reliquary bust of the apostle Bartholomew, a Scandinavian reliquary horn with relics of the apostles Thomas, Andrew and Judas Thaddeus, and the reliquary arm of Saint Tranquillus (a saint associated with the Theban Legion); relics of the holy bishops of Maastricht: the reliquary busts of Servatius, Monulph, Gondulph and Hubert; relics of holy women: the reliquary of the
