Concluding the comprehensive study of the Trinity, Pastor Terrie Beede summarizes the doctrine's essential points: God is three persons, each fully God, yet there is only one God. He revisits the Old Testament's implicit clues (plurality in divine names like Elohim, God's self-references in the plural, and the mysterious Angel of the Lord as a pre-incarnate Christ) and the New Testament's pervasive Trinitarian understanding in Jesus' baptism and apostolic teachings. Pastor Beede reminds listeners that historical errors like Monarchianism, Subordinationism, and Arianism highlight that any attack on the Trinity ultimately attacks either Christ's deity or humanity, underscoring the spiritual battle at hand and the importance of recognizing ancient errors in modern guises.
Pastor Beede then focuses on the church's historic understanding of the Trinity as one essence in three persons, a doctrine formally defined at the Councils of Nicaea (325 AD) and Constantinople (381 AD). He clarifies that these councils were not inventing doctrine but rather drawing out what was inherent in Scripture in response to heresies that emerged after the apostolic age. He reviews the concepts of Perichoresis (Circumincession), where the three persons permeate and indwell each other in social unity, and Monarchy, which maintains the Father's headship despite the Son and Spirit's equality in deity, power, and attributes, differing only in role or "economies". The distinct "processions" of God—the Father proceeding from none, the Son from the Father, and the Spirit from the Father through the Son—further define their relational differences within the Godhead.
The session's central theme shifts to the profound implications of the Trinity for Christian life, viewing it not just as a theological foundation but as a practical pattern for living.
1. The Trinity as a Foundation for Faith:
◦ Knowing God: Only God can fully reveal God; a created Christ could not truly and wholly manifest the Father.
◦ Personality and Self-Awareness: True personality, perfect love, and verified perfection necessitate a plurality of persons, illustrated by Augustine's "three I's" (I exist, I am conscious, I am aware of my consciousness) and the need for a qualified witness for validation.
◦ Justification and Atonement: Justification by faith alone and Christ's atonement are only possible through an eternal, fully divine, and fully human Christ, as no created or earth-born being could pay the perfect price for sin or provide eternal security.
◦ Worship: Worshiping a created Christ would be idolatry, affirming His full deity as essential.
◦ Scriptural Coherence: Denying any Trinitarian component ultimately denies the teachings of Scripture itself.
2. The Trinity as a Pattern for Our Lives:
◦ Marriage and Family: Ephesians 5:22-25 (husband as head, wife's submission, husband's Christ-like love) is expanded by 1 Corinthians 11:3 ("The head of Christ is God"). This reveals that headship and submission within the Godhead are characterized by equality in being and attributes, but subordination in role (Complementarianism).
◦ Trinitarian Model for Relationships: The Father, Son, and Spirit demonstrate perfect unity, communion, and counsel. The Father glorifies the Son and Spirit, and the Son eagerly carries out the Father's will without resentment. This models how husbands should lead—not domineeringly, but with respect, conferring with their wives and recognizing their equality in every way, viewing them as "overqualified" partners. Wives are called to a joyful, honored submission, understanding "functional subordination" as Christ's submission to the Father.
◦ Community (Body of Christ): Man was created male and female in God's image, reflecting both unity and plurality. The Trinity provides a blueprint for the church to live in unity, communion, and community (Acts 2:44-46), fostering an environment that attracts the lost.
◦ Individuality: Pastor Beede contrasts societal individualism (rooted in Lucifer's "I will ascend" - Isaiah 14:12-14) with the Trinity's emphasis on role and function over autonomy. Jesus lived to do the Father's will (John 4:34), and the Spirit does not speak of Himself (John 16:13). Believers are called to prioritize their relationships with God, family, and church, fulfilling their created role rather than living for self.
The session concludes by emphasizing that the Trinity is a vital, living doctrine for believers to embody—not merely intellectually, but with their hearts and lives, reflecting God's image to a lost world.
