The trinity is one of Christianity’s oldest and most mysterious doctrines. It has been a topic of much discussion and was in fact one of the first theological areas that theologians attempted to flush out. I’m not going to go into all of that here (mostly because a few books could be written on the topic) but the point I am trying to make ring home is that throughout the church’s history, this has been a topic of importance to the church. For this very reason, it is something worth understanding (as best we can).
