adjective
unholy
un-HOH-lee/ʌnˈhəʊli/
Offending what is regarded as sacred.
The priest condemns the destruction of the altar as unholy.

Etymology
Halig covered both sacred status and godly character. Negating it therefore gives not only ‘not sacred’ but also ‘impious’ or ‘wicked,’ the stronger moral meaning already found in Old English unhalig.
In context
the devil who had previously worked in the shadows now reveled in being openly worshiped feeding his pride that had been drained by Christ but Satan's Unholy Trinity was not yet complete
