As much as any New Testament book Acts is arguably a good candidate to be read as a vehicle for Trinitarian theology. It begins with the Ascended Christ who in that capacity appears to Paul. The extent to which this Messiah is to be understood as the Son of God can be gleaned from what is implicit in the book. The Spirit is not far behind and becomes a fully active presence both behind the scenes and in the foreground by dramatic intervention but also through commissioning and sending. Then there is the Father-the God of the nations as well as Israel, the Lord of history and the oekumene. The historical tradition of interpretation of Acts can lead the reader to see such theological matters as essential to the texts despite the best efforts of historical criticism to reduce it to merely a historical document - a window on cultures and ideologies, and of those narrative interpretations interested in stories and their relationship to other stories from their historical background. To take an emic approach means neither historical nor theological naïveté, but reading that approximates to how it was intended to be by those who wrote Acts and the other Scriptures.
