Monstrance clock may give first impressions of a scary timekeeping device. However, there is also a simple explanation. During the renaissance, Monstrance clocks were quite common in church ritual. The clocks themselves were ornate devices centered around a rotating ball and used for timing and planning ritual services. The word "Monstrare" having the original Latin meaning, " To show or display."

Given this band's primary subject material, their take on Catholicism, and their use of Fantasy, the lyrics seem to describe a fictional religious sermon. During this event, followers are shown a cloaked woman believed to be carrying the offspring of Lucifer. The song ends with a chant, encouraging listeners to join together, "For Lucifer's Son."

To understand the meaning of this message, if there is one, one must consider this band's subject, or "gimmick." While the message is somewhat debated, Ghost use satire to conceptualize that Catholicism, or possibly organized religion in general, has failed society. The stages of their concerts are set to display a mock catholic mass or sermon. The musicians wear shrouds, while the singer adorns a priest's robe, death mask, and papal hat with an inverted cross. They are a display of rejection to Catholicism, and possibly other organized religious sects. The imagery suggests that these sermons are not a worship of God in heaven, but a sacred display of reverence to the devil.

Ghost listeners are usually a group of people who feel that Catholicism and other religions have failed to lead society to any positive outcomes. They may feel rejected by the church, or wary of many catholic scandals of recent times. Some may follow these performances as a way to feel empowerment over organized religion, while some may just have a fascination with the occult.

Whatever the message, Ghost's music has no doubt created controversy amongst Catholics and other religious leaders. Just like all the controversies Rock and Roll has spawned now since the 1950s.
