If you are a confirmation student looking for a good way to sidetrack your pastor, you could do worse than asking them to explain the Trinity. The three persons of the Trinity: Father, Son, and Holy Spirit, can be difficult to understand individually. Many picture God as an old man who is alternately disinterestedly distant and vengeful, Jesus as a person who arrived at a stable at Christmas and was hung from a cross sometime around Easter, and the Holy Spirit as… Well, there are no secular traditions around Pentecost, so we don’t normally give much thought to the Spirit. One might also think that God became Jesus so that people could see him then became the Spirit after returning to heaven to sit next to himself and wait to come back.
