'''===Meaning===In an interview with U. Magazine published April 1994, [[Trent Reznor]] spoke about the meaning behind the lyrics of this song:<blockquote>"I was trying to explore some of the paranoia I have as a sexually active person in the age of AIDS," he says of "Heresy."''' "I guess I feel cheated for not growing up in a more liberated era. At the same time, what gets me mad is the third track on way the right wing has used the 'convenience'of this epidemic in helping to promote their own agenda."

*Production: [[Trent Reznor]]

Released by Reznor through his [[remix.nin.com ]] account, this is an unmastered and vocalless version of the album cut.

'''''Running Time: 5:19''''' This remix samples "In Suburbia" and "Television Believers" by from Aron Ranen's ''ReligionIn Suburbia''.

'''''Running Time: 5:32''''' This version splices up the bass track and the drums to create a dancier beat (like the "Slate" remix of "[[Head Like A Hole (song)|Head Like A Hole]]"). The choruses are much less layered. On June 22, 2011, Joseph Bishara commented on the creation of the remix on his facebook page: "It was a great time - working at Bryan Adams studio in Vancouver with Dave Ogilvie and Anthony Valcic - programmed around the tracks, and we recorded hours of live at the console mixes, later edited into Heresy and Reptile remixes." A slightly extended version of this mix appears on the promo-only vinyl of ''Closer To God''.

* Manipulation: [[Dave Ogilvie]], [[Anthony Valcic]], [[Joe Bisara]]

This demo version is found on the 2-disc Deluxe Edition of ''The Downward Spiral.'' The vocals in the verses are solely whispered, rather than both whispered and sung in Reznor's high register as on album version. As well, the tempo is slower(105 instead of 115 BPM), and the structure is altered, featuring a differently-arranged introduction.

This song has been played very faithfully to the album version since 1994. However, though it was can be considered a setlist rarity until because it has only been played on the [[Self Destruct Warm-up]] tour (twice), [[Performance 2007]] tour and [[Wave Goodbye Tour]] in 2009.The missing line from the studio version, "Will you die for this", was used in the Wave Goodbye tour.

The last line, rather than being sung at the end of the sungsong, is repeated during the bridge, as evidenced in live performances.
