Oriental Orthodoxy is a group of Christian churches that believe in Jesus Christ and follow his teachings. They are mostly found in the Middle East, Asia, and Egypt, which is where the word 'Oriental' comes from.
These churches were created in the early days of Christianity, and they have followed a different path than the other big group, which is called Eastern Orthodoxy.
They believe in some different things about Jesus and his teachings, but the biggest difference between Oriental Orthodoxy and other groups is that they think Jesus has one nature. This means that they don't believe that Jesus had two parts, one human and one divine. They think that his human nature and his divine nature were combined into one nature, which is something that other groups don't agree with.
They also have different ways of doing things in their worship. One example is that they use different music and prayers than other Christian churches. They also have different rituals and symbols that are important to them.
Even though they're different, Oriental Orthodox churches still believe in the same core teachings as other Christian groups. For example, they think that Jesus died on the cross to help humans and that forgiveness is important.
In summary, Oriental Orthodoxy is a group of Christian churches that have some different beliefs about Jesus and different ways of worship, but still share the same core values as other Christian groups.
