The Red Cross of Constantine, or more formally the Masonic and Military Order of the Red Cross of Constantine and the Appendant Orders of the Holy Sepulchre and of St John the Evangelist, is a Christian fraternal order of Freemasonry. Candidates for the order must already be members of Craft Freemasonry (lodge) and Royal Arch Freemasonry (chapter); they must also be members of the Christian religion, and proclaim their belief in the Christian doctrine of the Holy Trinity. The Masonic and Military Order of the Red Cross of Constantine is a three-degree Order of masonry, and with its "Appendant Orders" a total of five degrees are conferred within this system. Installation as a “Knight of the Red Cross of Constantine” is admission to the Order’s first degree.

The ceremony is short and simple, but teaches valuable moral lessons to the candidate, based upon the story of the Roman Emperor Constantine the Great, and the Battle of the Milvian Bridge. Second Degree – Priest-Mason (or Installed Eusebius) On election to serve as Viceroy (the second in command of a Conclave), a member must be admitted to the second degree, by which ceremony he becomes a Venerable Priest-Mason, or an Installed Eusebius. This ceremony is performed in a ‘College’ of Priests-Mason. A College is the name for any assembly of members of the Order’s second degree. The ceremony is highly spiritual in nature, and incorporates more overtly religious symbolism and ritual. Having received this degree the Installed Eusebius or Priest-Mason is entitled to serve as Viceroy in his own, or any other, Conclave or College. In general this degree may only be conferred on those elected to serve as Viceroy of a Conclave, although exceptions are possible by dispensation. Third Degree – Prince-Mason On election to serve as Sovereign (the leader
