While widely accepting the restoration doctrine he espoused during the healing revival, his divergent post-revival teachings were deemed increasingly controversial by his Charismatic and Pentecostal contemporaries, who subsequently disavowed many of the doctrines as "revelatory madness".

句中的as "revelatory madness"，这一短语是作宾语补足语吗？但是和动词disacvow搭配应该如何理解？希望解答，谢谢。
