The East Syrian Rite is a way of practicing Christianity that has been around for a long time. It's kind of like a special way of doing things that is different from other ways people practice Christianity.
When you go to church and see people singing and praying, they might be doing things in different ways depending on which type of Christianity they follow. The East Syrian Rite is one of those ways.
They have their own special songs, prayers, and rituals that are different from other types of Christianity. Some things might look familiar, like the way they might hold their hands or make the sign of the cross, but there are also some unique things they do that you might not see in other churches.
Just like other types of Christianity, the East Syrian Rite is all about worshipping God and following Jesus. They use their own special way of doing things to help them connect with God and feel closer to Him.
