Thy Mighty Contract is the debut studio album by Greek extreme metal band Rotting Christ, released in November 1993 on Osmose Productions.

[3] Rotting Christ plays fast black metal in the Greek style, which was, according to AllMusic journalist Eduardo Rivadavia, “slightly over-reliant on furious blastbeats”, but showing “a budding flair for melody”.

[2] Chad Bowar of About.com describes the style as black metal which “took on a melodic, slightly heavy metal-ish format“, with a “limited supply of rhythm blasting and lifeless tremolo riffing”.

[4] Allmusic journalist Eduardo Rivadavia called Thy Mighty Contract “a promising first long-player”, although “the album's production may have been somewhat subpar, and its songs slightly over-reliant on furious blastbeats, but none of this mattered a lick to hardcore extreme metal fans”.

[2] About.com featured the album as a Retro Recommendation and criticised the drums for being “too loud, and given the repetitive beats played, it becomes distracting at times.
