Saint-Trinity, or Sainte-Trinité, is a Christian doctrine that describes the nature of God as three distinct persons in one essence: God the Father, God the Son, and God the Holy Spirit. This belief is central to many Christian denominations, emphasizing the unity and co-equality of the three persons. The concept of the Trinity is often illustrated through various symbols, such as the triquetra or the triangle, which represent the interconnectedness of the three persons. The doctrine is rooted in scripture, with references found in the New Testament, particularly in the teachings of Jesus Christ and the writings of the apostles.
