Okay kiddo, so the Parson's Handbook is a book that helps priests and pastors know how to do their job. It's a guidebook that tells them what to say and do during church services, like weddings, baptisms, and funerals.
It also gives them advice on how to take care of the church and the people who go there. This means making sure everything is clean and organized, and that everyone is treated with kindness and respect.
The Parson's Handbook has been around for a very long time, and it's still used by many pastors and priests today. They use it to help them do their job well and serve their community in the best way possible.
