In a parallel world known as Tellus, a controversy erupted over the rite of light. This controversy turned on interpretation of the words: "I am the light."
There were some heretical schismatics as well as some schismatical heretics who took the words figuratively. However, an Inquisition put a speedy end to their unspeakable impieties.
That, however, left many questions unanswered. When the Savior became a photon (at the words of consecration, “Lux ecce surgit aurea”), what kind of photon did he become?
The Infrareds took one position while the Ultraviolets took another.
There was yet another faction, known as the X-rays (which split into two groups, the Soft X-rays and the Hard X-rays), but no one under the age of 21 is allowed to consult the illustrated history of that particular sect.
His Holiness, Pope Terahertz IV, convoked the Council of Ozone to resolve the controversy before the rift was irreparable. But at that point I lost my uplink to Tellus, so I can’t tell you how the proceedings went until transmission is restored.
