Anthony Thiselton has long been recognized as a leading voice in the area of hermeneutics. In this essay I engage his latest monograph on hermeneutics as it relates to doctrine. I offer some comment for clarification on hermeneutics of doctrine and horizons of understanding. Although Thiselton's work offers much of value to the Christian communities, his argument that the book of Acts is unable to provide normative doctrinal paradigms for those communities runs counter to his argument that the canon serves as a foundation for the genesis and development of doctrine.
