The album received generally positive reviews from music critics. AllMusic described the album as a "powerful statement of intent and a hugely cinematic amalgam of heavy metal subgenres", with the band delivering "its most crucial outing to date, one that's both devastating and galvanizing." The review also noted the prominent influence of Iron Maiden and Judas Priest on the album's more melodic musical style, and compared Reverence to Metallica's Black Album. Already Heard rated the album 5 out of 5 and said: "Reverence could have broken Parkway Drive and torn their mantra to shreds. The physical and mental pain that builds up these tracks' foundations could've left them exasperated and drained, but they've persevered and turned despair into the finest album of their career. These songs are anthems of struggle, loss, and retribution, destined to turn Parkway into every festival's confirmed headliner." Distorted Sound scored the album 9 out of 10 and said: "The fervour on social media around Reverence has certainly been more divisive than before, and it would not be a surprise to see some of those that have followed PARKWAY DRIVE from the very beginning to turn their backs on the Australians, but the army of followers who will join in support will far outnumber the deserters. The biggest band from Down Under since AC/DC are at the very top of their game and are only going to get better." On the opposite end of the spectrum, Connor Atkinson from Exclaim! gave the album a 3 out of 10, stating "the sole digestible tracks are 'In Blood' and 'Absolute Power'. The former is a rehash of ideas from 'Carrion', off Parkway Drive's seminal 2007 release Horizons, while the other recalls Biohazard at their tamest, which in itself could lead a listener astray, depending on how you take your metalcore tea." The review ended by saying "the paychecks from European summer festival season must be very rewarding, because that is the only audience that will be able to swallow any of Reverence's brooding cowboy nonsense." Alex Sievers from KillYourStereo gave the album 80 out of 100 and said: "Is Reverencethe best Parkway Drive album? No, but it's a good record nonetheless, one that sees the Australian legends not giving a fuck what anyone else thinks and really trying to push the boat out for themselves. Is the band's sixth album the 10/10 release that every other publication has labelled it as recently? Nah, not really, but it's a bold body of work from a band that suffered immensely prior to its creation, pulling their personal pains together to create something engaging and interesting." NME likewise praised the album for its more melodic approach, singling out singer Winston McCall's vocal performance for particular praise, and concluded that "Reverence is a record for arenas, and Parkway Drive have finally – and perhaps unexpectedly – become the modern metal band who deserve to fill them." Simon Crampton of Rock Sins rated the album 10 out of 10 and said: "This is everything Parkway Drive have always threatened to be and a very big sign of everything they are about to become. This is the album that puts them into arenas and into the history books as one of the greatest bands of their generation." Wall of Sound gave the album a perfect score 10/10 and saying: "Well, that was Reverence and holy fuck what an experience it was. Parkway Drive are no longer the boys from the Byron Bay Hardcore scene, they're now the men taking on the worldwide Heavy Music industry and proving they're here to stay. It's so hard to fault this album when you think about everything they've produced. It's raw, heavy, soothing, calm and hectic in so many ways and styles. They've risked tackling something they haven't done before and completely blown expectations out of the water. This isn't a new album of churn and burn music, this is a fucking strategically orchestrated masterpiece that'll be played for years to come and hopefully several songs from it will become staple go-to future classics in years to come."
