Okay kiddo, so you know how when a grown-up goes to church, sometimes they stand up and talk to everyone? Well, a recorded minister is someone who does that a lot and has been doing it for a long time.
And you know how when you draw a picture, you might show it to your mom or dad and they take a picture of it with their phone? That's kinda like what recording a minister is - it's like taking a picture of them while they're talking so that other people can hear it later.
Sometimes people want to listen to a recorded minister because they like the things they say and want to hear them again. And other times, people might not be able to go to church in person, so they can listen to a recorded minister instead.
So basically, a recorded minister is someone who talks in church a lot and people want to listen to them even when they're not there.
