The track "Malign Paradigm" is a tribute to the Swedish black metal band Malign, and their track "Ashes and Bloodstench". "Drink the Devil's Blood" is a re-recording of a song of the same title appearing on the band's first album, Infernal Battles. The re-interpretation of this station contains completely new lyrics dealing with a Eucharistic theme, in keeping with the more cerebral lyrical approach of this and subsequent releases.
The artwork is "both a statement on the Logos, providing metaphysical keys to a certain approach on reality, and a statement on our faith and it's concrete anchors and applications in the world as every human being can actually experience it. But keep in mind: the light that illuminates us is the very same that blinds us too." The band note that the line "The heart of a lost angel is in the earth" from the track 'Sola Fide I' is strongly linked with the artwork. The line is taken from Elizabeth Barrett Browning's poem "A Drama of Exile", which is a retelling of the exile of Adam and Eve from the Garden of Eden and Satan's role in it.
Musically, it represents a massive departure in sound from the band's previous work, both for the increase in recording and production quality as well as for the pursuit of far more avant-garde and experimental directions than the band's previous work. The album incorporates Gregorian chants, chaotic moments and significant use of dissonant and atonal riffs and chord structures. The album was also originally intentionally structured in the manner of 1970s double albums, with each LP side opening with a "prayer" (side four, which opens with "Carnal Malefactor", being an arguable exception). The album was inspired by Christian sources (often Catholic), particularly in its metaphysical discussions. The band frequently quote passages from the Christian Bible, for example 'Third Prayer' quotes Chapter 17 of the Book of Jeremiah: "Thus says the LORD, “Cursed is the man who trusts in mankind, and makes flesh his strength, and whose heart turns away from the LORD." 'Sola Fide' is Latin for 'faith alone', which references Martin Luther's doctrine emphasizing the primacy of faith over action in ensuring salvation. "Hétoïmasia" is Greek for "preparation", which references the empty throne awaiting Christ's return.
