Which article affirms the belief in one God eternally existing in three persons?

The belief in one God eternally existing in three persons is a foundational doctrine in Christian theology, specifically recognized in Trinitarian beliefs. The correct choice affirms this concept by articulating the nature of God's existence as a single divine essence subsisting in three distinct persons: the Father, the Son, and the Holy Spirit. This understanding is crucial in discussions of the Trinity, emphasizing not only the oneness of God but also the relational aspects of the Godhead, which are important for understanding the Christian faith and its teachings.

The context of the Trinitarian doctrine, as presented in this article, serves to unify believers around a central truth of the Christian faith, outlining the importance of each person of the Trinity in relation to salvation and the role they play in the lives of believers. Knowing this foundational principle is essential for anyone studying or involved in church leadership and exhortation within the Church of God.
