The family serves as the primary and foundational place of education for Christians. It plays a crucial role in shaping values and nurturing relationships with God. This discussion focuses on the concept of the Triune God, which serves as a model for the family life of educators. Using the Interpretative Phenomenological Analysis (IPA) approach, the researcher aims to explore various aspects of educators' family life associated with the teachings of the Council of Nicaea. Just as the Father and the Son exist in the fellowship of the Holy Spirit, families are also called to embody love, share, and cultivate close relationships. Additionally, the ideals of unity in diversity and self-giving reflect the nature of the Trinity within the family. This study seeks to illustrate how the family, regarded as a "Domestic Church" (Ecclesia Domestica), can mirror the love of the Triune God. Furthermore, the teachings of the Council of Nicaea hold significance in family life, demonstrating how families can exemplify the love and unity inherent in the Triune God.
