The Holy Trinity
Father - Son - Holy Spirit
The doctrine of the Trinity means that there is one God who eternally exists as three distinct Persons — God the Father, Jesus Christ the Son, and the Holy Spirit.
The Trinity represents the Christian doctrine that one God exists as three co-eternal, distinct, yet inseparable Persons: God the Father, Son (Jesus Christ), and Holy Spirit, all sharing one divine essence or nature, not three separate gods. It signifies God's complex, unified being—one "What" (essence) and three "Whos" (Persons) revealing God as the creator (Father), redeemer (Son), and sanctifier (Holy Spirit) working together for humanity's salvation and relationship with Him.
