The grammatical key — singular karpos, not plural fruits
Galatians 5:22 reads in Greek: ho de karpos tou pneumatos estin agapē, chara, eirēnē — "but the fruit of the Spirit is love, joy, peace…" Karpos is singular. The list of nine attributes that follows is not a list of nine separate fruits but a single fruit visible from nine angles. This stands in deliberate contrast to charismata (the spiritual gifts of 1 Cor 12), which are explicitly plural and distributed: "to one is given by the Spirit the word of wisdom; to another the word of knowledge." Gifts are distributed; fruit is unified. Every believer bears the whole fruit. No believer has all the gifts. The grammar is the theology.
