The following was posted on the Official Site of Celtic Frost regarding the dismissal of Unala from the band.

"CELTIC FROST and Erol Unala have chosen separate paths on the verge of the release of their new album, titled 'Monotheist'. Unala, a longtime collaborator in APOLLYON SUN with CELTIC FROST founding member Tom Gabriel Fischer, has been a crucial factor in the renaissance of Swiss avant-garde extreme metal band, CELTIC FROST.

"The necessity of this sacrifice became evident during the creation of 'Monotheist'. The obligation to his biological family, the responsibility he took on as a patriarch, has led him to lose sight of this family in spirit. We should not blame him. But we did. We have failed to lead him back to the fold, and this lost son did not find his way home. Proof of his creativity will always remain with us in the form of 'Monotheist', though.

"The greater the sacrifice, the more the loss will be felt. This responsibility is ours. Although the separation has lit the pyre and the smoke is rising, we all feel bound by the code of honor that our past decrees.

"Will our God accept this offering?

"Only death is real!"
