The Athanasian Creed famously confesses, “We worship one God in Trinity, and Trinity in Unity; Neither confounding the Persons nor dividing the substance." But what exactly does this mean that God is one and yet three persons? And why is The Athanasian Creed so concerned about the doctrine of the Trinity as it relates to our salvation? In this episodes Kirk is joined by Brandon Smith to discuss these questions and more!

(We apologize for the poor quality audio on Kirk's end. His computer was experiencing a technical problem during the recording which affected the audio.)

Delegates from throughout the ecumenical (universal or "catholic") church met in Chalcedon in 451 AD to address the emergence of certain heresies surrounding the person and nature of Christ. Some were teaching that Jesus merely took on the material aspects of a human body (Apollinarianism). Others so distinguished Jesus' humanity and divinity that they conceived of each as involving a distinct person (Nestorianism). Finally, some so emphasized Christ's unity that they spoke of his divinity blending with his humanity to form a new mixed nature (Eutychianism or Monophysitism). The Council of Chalcedon thus responded to these errors, producing a confession of orthodoxy known as The Chalcedonian Definition (or the Symbol of Chalcedon). It affirmed that the incarnate Christ is one person with both a human and divine nature.

But why does this statement matter, and are its distinctions all that important? What, if anything, can we learn from it today? Dr. Stephen Wellum joins Kirk in this episode to discuss the meaning and significance of this important historical document.

What was is The Nicene Creed and why does it matter? In this episode, Dr. Matthew Barrett joins Kirk to discuss the historical circumstances that gave rise to the creed as well as some of its central confessions. They discuss why it matters that Jesus is "of the same substance with the Father" and "eternally begotten" but "not made." The Nicene Creed gives us categories by which to understand God's self-revelation in scripture as it finds its center in the saving work of Christ.
