Daniel M. Garland Jr. interprets John’s Bread of Life discourse through Aquinas’s theology of the divine missions, arguing that eternal life consists not in abstract knowledge but in a personal, experiential participation in the Father and the Son. Jesus, who possesses life in himself as the Word, is sent by the Father to communicate divine life through Baptism, the Eucharist, and the Holy Spirit. Eating Christ’s flesh and drinking his blood establishes a mutual abiding: Christ dwells in the believer, and the believer is transformed into Christ rather than Christ into the believer. The Eucharist therefore makes the risen body of Christ the believer’s true temple and enables Christians to share in the Son’s filial relationship with the Father. This union, compared with a branch’s dependence on the vine, bears fruit in sacrificial love and present participation in eternal life. Aquinas’s account of mission clarifies that the Son’s being sent signifies procession from the Father without inequality, while the invisible missions of the Son and Spirit bring sanctifying grace. Through faith, charity, and the Spirit’s gift of wisdom, believers acquire an affective “connatural” knowledge of God, becoming children of God and participants in Trinitarian life.
