The Holy Trinity is a well-known doctrine (teaching) about the nature of God in most Christian churches.
This idea is used to explain that there is one God who is experienced as three distinct persons—God the Father, God the Son (Jesus), and the Holy Spirit. Those persons share the same essence and qualities.
Each person in the Trinity has the same qualities as God because they are each fully God. None of them is less God than the other.
The Trinity is a complex idea that Christians across history have spent a long time debating and figuring out. Not all Christian groups accept this idea. Many Christians say they do not understand it.
