"三位一体" (Trinity) is a Christian doctrine that describes the nature of God as being one essence in three distinct persons: 父 (the Father), 子 (the Son), and 圣灵 (the Holy Spirit). This concept emphasizes that while these three persons are unique, they are all fully and equally God, sharing the same divine essence. The doctrine of the Trinity is foundational to many Christian beliefs and is often summarized in the phrase "one God in three persons." It is a central theme in the teachings of various Christian denominations, influencing their understanding of God's relationship with humanity and the world.
