Read Colossians 1:18. What is the connection between the idea of Christ as the head and Him as the “beginning”?
In Hebrew the words for head (roʾš) and beginning (rēʾšît) are related. The first instance of the latter word in Scripture is in Genesis 1:1: “In the beginning [_rēʾšît_] God created the heaven and the earth.” Jesus is head of humanity and of the church, not only because of the Incarnation but also because He is the Creator.
