There are several interpretations of this acronym. Here, we look at the most common.
When crucifixions were commonplace, it was customary to affix a board at the top of the cross detailing the crimes of the crucified person. This board was called titulus cruces hence the name Titulus Cross or Proclamation Cross. The plaque is stylised as an upper beam on several cross types, including the Patriarchal Cross, Orthodox Cross and Papal Cross. Sometimes the lettering is carved onto the main cross beam (patibulum), without the additional upper bar. We still refer to this as a Titulus Cross.
The inscription is usually 'INRI' but other lettering can be used (see Lettered Crosses).
About 2,000 years ago
Roman procurator Pilate was reluctant to crucify Jesus because he could see no real justification. Indeed, he would rather have acquitted Jesus, but there was intense pressure for him to assert his authority and punish those who were deemed to have broken the law. He was anxious that no negative reports about his performance would be relayed back to the emperor.
At that time, Jews had a treaty with Rome for self-government. The Jewish priests complained to Rome that the impact Jesus was having on the populace was so intense that people were regarding him as royalty. The existence of a monarchy went against the treaty and Jesus was therefore interfering with their self-rule. Pilate challenged Jesus to deny this, but with no denial forthcoming, Pilate announced a 'guilty by default' verdict and the priests demanded the death penalty. The crime for which Jesus was crucified therefore was 'King of the Jews', and this was duly painted on the titulus.
The inscription was written in Latin (the official language of the Roman Empire), Greek (the international language of culture) and Hebrew (the religious language of the Jews). The Latin is: IesvsNazarenvsRexIvdæorvm which in English translates to: 'Jesus the Nazorean, King of the Jews' p>
About 1,000 years ago
In the Middle Ages the primary language in church was Latin. People were familiar with the IesvsNazarenvsRexIvdorvm phrase and it became customary for artists to abbreviate the lengthy wording to the initial letters: INRI.
A fragment of the titulus from the True Cross (the cross on which Jesus Christ was crucified) still exists and lies in the Church of Santa Cruces in Rome. Or at least, many people believe that a small wooden block, less than a foot long, is an original relic from 2,000 years ago.
Equally, many others hotly contest this. However, if it's true that the Roman emperor Constantine sent his mother, Helena, as a missionary then it may be an authentic relic. Helena is said to have taken the titulus of Jesus' cross as an aid in spreading Christianity throughout the Roman Empire.
Many translations say the title was written in Hebrew but it's more likely it was Aramaic; the language spoken by most Judæans at that time.
In the Eastern Orthodox Church, the letters INBI reflect the equivalent Greek text Iésous o Nazóraios o Basileus tón Ioudaión
There are several other interpretations of INRI, including:
- Igne Natura Renovatur Integra - 'By fire nature is restored in purity'; a medieval Rosicrucian motto refering to the inner fire of the spirit, and for the Masons, the regeneration of nature by the influence of the sun symbolizes the spiritual regeneration of mankind by the sacred fire (truth and love).
- Iustum Necar Reges Impios - 'It is just to exterminate or annihilate impious or heretical kings, governments, or rulers'; printed on the Jesuit flag; not quite in keeping with Matt. 22:36-40.
