Why should this matter to me?
The Trinity has shaped Christian worship, prayer, art, music, and belief for almost two thousand years. If you’ve ever wondered why Christians baptize “in the name of the Father, and of the Son, and of the Holy Spirit,” or why the early Church argued so passionately about who Jesus was, then understanding the Trinity helps make sense of Christian history. Even if you don’t identify as Christian, it’s one of those ideas that’s difficult to understand our culture without knowing.
