The Most Holy Trinity—Father, Son, and Holy Spirit—uses heresy. On the surface, this is a frightening statement. But through the challenge of Christological heresies, the early church was moved to the task of articulating the faith once for all handed down to the saints. As a result of these heresies, the church realized that it had to lay out biblically, with nuance and precision, who Christ is. This nuance and precision was geared toward answering these heresies with "no," and resulted in the saints through the ages knowing Jesus better. As it was then, so it is now. The church today, in sync with the Scripture and the apostolic tradition founded upon Jesus, needs in part to articulate biblical Christology in a way that specifically addresses modern-day heresies so that we may know Christ better, more deeply. In Knowing Christ in the Challenge of Heresy, Steven Tsoukalas lays out several modern-day heretical Christologies and answers them biblically with nuance and precision. Readers will not only find a documented cataloguing of specific heresies, but also chapters on Christology found in books of the Bible.
