Ok kiddo, so the Synod of Beth Lapat was a big meeting that happened a long, long time ago. Think of it like your class having a really big meeting, but instead of just talking about school stuff, they talked about really important things for their community.
The people who were at this meeting were called bishops, kind of like the head teachers of churches back then. They talked about how to make their churches better and help more people understand their religion.
They talked about things like how to baptize people and how to do weddings. They also talked about rules for people who wanted to become bishops, like how they had to be good and follow the rules themselves.
Overall, the Synod of Beth Lapat was an important meeting that helped make the church better and more organized.
