A theological concept describing human participation in trinitarian life through Christ and Spirit, where believers are drawn into the mutual love and communion of Father, Son, and Spirit while maintaining their created distinctiveness. This concept provides theological foundation for understanding salvation as communion rather than merely legal transaction, challenging both individualistic spirituality that isolates persons from relationship and collectivist approaches that absorb persons into undifferentiated unity. Trinitarian Participation supports
Interindependence by demonstrating how authentic personhood emerges through relationship rather than isolation, and directly addresses
Practical Atheism by connecting belief with participation in divine life rather than merely intellectual assent.
