How do we know that God is revealed in the mystery of the Holy Trinity?

The doctrine of the Trinity—the understanding that God exists as one essence in three distinct persons: Father, Son, and Holy Spirit—is a divine mystery revealed through Scripture. Instead of being deduced by human reasoning, this profound truth is disclosed in various biblical passages, such as John 1:1 and Genesis 1:26, which highlight both the unity and distinction within the Godhead. As believers, we embrace this mystery by faith, acknowledging that it is not our logic that gives us understanding but rather God's revelation of Himself in His Word and through His actions in history.
