Trinity

The New Apostolic Church affirms the classical doctrine of the Trinity as taught in the ecumenical creeds. God exists as three distinct persons—the Father, the Son, and the Holy Spirit—who share one divine essence or nature. The church's catechism and liturgical practices reflect this Trinitarian understanding, rooted in Scripture and traditional Christian theology.

The NAC teaches that the Father is the eternal source of the Godhead, the Son is begotten eternally of the Father, and the Holy Spirit proceeds from the Father and the Son. These three are co-equal in power, glory, and eternity, though they are distinct persons. The Trinity is not a human invention or a compromise doctrine but the revealed truth about God's nature.

While the NAC's distinctive claim regarding living apostles and sacraments for the departed represents a departure from mainstream Christianity, its Trinitarian theology remains conservative and orthodox. The church does not challenge the foundational Trinitarian doctrine affirmed by the early ecumenical councils, and this commitment to Nicene orthodoxy is central to NAC self-understanding.
