The story behind it
Word for word the phrase says “the weapons of Christ”. It is not a line from an ancient author but a term from Christian art history, used for the objects connected with Christ’s Passion and crucifixion.
In late medieval devotional art and heraldry these objects were gathered and displayed as Christ’s own ‘weapons’ or coat of arms: the cross, the nails, the crown of thorns, the lance and similar items. The military language is deliberate: the Passion is presented as a victory over evil, not a defeat.
The theme survives in church paintings, stained glass, carvings and manuscripts, and art historians still use the Latin term for such images.
How to use “Arma Christi”
It suits religious art, a church-themed caption or print, a card message for a Christian audience, or a tattoo for someone drawn to medieval iconography. It also works as a title or keyword when writing about the visual history of the Passion.

Common mistakes
- It does not mean weapons used by Christ or in his name. “Of Christ” points to the instruments of his Passion, shown as symbols of victory.
- Arma is a neuter plural noun with no singular here. Do not write “armum” or “arma” as a single weapon; the singular would be a different word (telum, for example).
- It is not a classical or biblical quotation. It is a later iconographic and devotional term, so do not credit it to a Roman author or to the Vulgate.
- The phrase is also known in English as the Instruments of the Passion. Check which one your context needs, as the Latin term is the more specialist label.
