Yesterday, in our Reformed confessions course, we were considering Belgic Confession articles 18 and 19 on the incarnation and the two natures of Christ. One of the best ways to understand what the Reformed confess under these heads of doctrine is to consider the Definition of Chalcedon (AD 451) and the Athanasian Creed. As we worked our way through our shared inheritance from the church universal, we came across article 33 of the Athanasian Creed as quoted above.
