The band refers to its style of Christian metal as "Gorship" – a portmanteau of gore and worship. The band also clarify on their MySpace blog that "Gorship" is their way of worshiping God through their gore sounding music; not worshiping "gore" as some are led to believe.
The band also created their own symbol called the "Repentagram" combining the words repent and pentagram. The band explained the Repentagram with the following:
"We’ve gotten a lot of mail questioning the Repentagram Logo, I would like to take time right now to explain it to you all. First off we are a christian band and a real one at that, we would never put something out that had satanic meaning or anything negative. We thought up the word "REPENTAGRAM" basically putting two words together. 1. REPENT (meaning: to feel such sorrow for sin or fault as to be disposed to change one’s life for the better; be penitent.) 2. PENTAGRAM (which in the dark metal world is a satanic symbol.) Since we are a Christian death metal band we wanted to think up something clever; thus the Repentagram came into thought. It is not the same amount of sides as a pentagram, we are going for making a Christian death metal symbol. Just like we created the word "GORSHIP" (which as you all should know, does NOT mean worship gore, it means worshiping God through our Gore sounding music) the Repentagram is just the new word. Please pass this information along to anyone you may know that thinks anything more than it really is."
