The language of Chalcedon

A few years back, I put together this visual summary of the terminology the Council of Chalcedon (451 AD) used to express the biblical doctrines of the Trinity and the two natures of Christ. This is one of the most important councils of Christian history, because it clearly confirmed the reality of God revealed in Jesus Christ and established language and norms that Christians have used ever since.

I put it together because I didn’t have a Greek philosophical background and I was often confused by all the mention of “person”, “nature” and “being” – it’s meant to be an aid to reading the history and creeds.

If there are any Patristic experts out there who happen to read this and would like to comment or correct me, please go ahead!
