Despite selling over 450,000 copies, the album has never been certified gold by the RIAA. In October 1990, Testament released their fourth studio album Souls of Black. Although reviews were mixed, the album managed to sell respectably, in no doubt largely off the strength of the single title track, and saw the band perform on arena tours, including the European Clash of the Titans tour with Megadeth, Slayer and Suicidal Tendencies. Testament supported Souls of Black with two North American tours, opening for Judas Priest on their Painkiller tour from October to December 1990, and Slayer on their Seasons in the Abyss tour from January to March 1991.

In support of The Ritual, Testament toured Europe and North America, headlining their own tours, as well as opening for Iron Maiden on their Fear of the Dark tour, and Black Sabbath on their Dehumanizer tour. However, the success of the album did
