The Catholic Church has always emphasized the importance of memorials that mark the liturgical year. In fact, unlike other religious traditions, since the Middle Ages the Catholic calendar proposes a solemnity for each day of the year, through the commemoration of a feast or saint.
Being able to relive the joy of events such as Christmas or Easter, for example, or indeed, be inspired through prayer by the example of those who lived the call to holiness before us, is an important source of sustenance for the People of God on earth who know that those in Heaven can intercede on their behalf.
There are many charisms at work in the Church, as is recalled in the Dogmatic Constitution on the Church Lumen Gentium: "The Spirit guides the Church to all truth (cf. Jn 16:13), The Spirit guides in way of all truth and which He unified in communion and in works of ministry, He both equips and directs with hierarchical and charismatic gifts and adorns with His fruits. (cf. Eph 4, Il-12; 1 Cor 12.4; Gal 5, 22)" (Lumen Gentium, 4a). Therefore, it follows that different institutions are associated with particular feasts and the commemoration of certain saints.
The Equestrian Order of the Holy Sepulchre celebrates the following feasts with particular joy:
● The feast of the Blessed Virgin Mary, Queen of Palestine (October 25)
● The feast of the Holy Cross (September 14)
● The memory of St. Pius X (August 21)
● The memory of St. Helena (August 18)
