I'll do a one-by-one, objective analysis on the theme of each song and listen to any contrary cases and adjust my ratings accordingly if a compelling counter-argument is provided:
Apocrypha - Penance (Keep The Faith) - no lyrics available, but I could make out no specific references to the Bible or its contents
CAULDRON BORN - Crusader - a song about a soldier fighting in a religious war on the side of Christianity, and is written in a way to imply that both state and religious motivation are present, but primarily describes the fight itself
Sadus - Oracle of Obmission - anti-religious, no references to Christianity, and not even exclusively there; "I'm the voice of the media / The power of propaganda" or " A system of conformity / Forfeit of your liberty", this is a song about brainwashing in general
Messiah - The Choice - a song implicitly (but obviously) about free will in the context of salvation and belief in God/Jesus
Forsaken - Via Crucis (The Way of the Cross) - Bible stories
Manilla Road - Divine Victim - a song about Joan of Arc, and how she suffered after a relatively secular war under a system driven by Christianity (which most courts of the time were)
Trouble - Run to the Light - hippie stuff with religious allusions to salvation, but almost humanist in motive ("But when I die, I know I will find my way" or "All are welcome, on the other side")
October 31 - The Verdict - a song about a man wrongly accused of a crime and executed, followed by religious frustration over not being saved
Saracen - Horsemen of the apocalypse - Bible stories
Icecross - Jesus Freaks - anti-Christians, not even anti-Christian
Tristitia - Christianic Indulgence - Satanism/occult, containing vague/implied mention of others following Christianity
Tourniquet - Ruminating Virulence - aka "God works in mysterious ways", more of a meme than a tenet of the Bible, but it's pervasive thinking in Protestant/born again groups
W.A.S.P. - Babylon's Burning - Bible stories
Immolation - Nailed to Gold - Bible stories, modified to provide anti-Christian sentiment
