By the church is this wisdom made known to the angels, either as the doctrine of the gospel is delivered unto it, or as it is gathered thereby. And what is this wisdom of God that is thus made known to principalities and powers? It is, that “the Gentiles should be fellow-heirs and of the same body with us,” verse 6. The mystery of adopting sinners of the Gentiles, taking them from their slavery in the family of the world, that they might have a right of heirship, becoming sons in the family of God, is this wisdom, thus made known. And how was it primitively made known? It was “revealed by the Spirit unto the prophets and apostles,” verse 5.
