By analogy, in our 1st reading Apostle Paul is very excited about the mystery of Christ which had been revealed to him like never before, that is the Gentiles, you and I, are coheirs in the promise God made to Israel in the Old testament, all of us together in the same Body in Jesus Christ through the Gospel. Why, so that the manifold wisdom of God might be made known through the Church, to the principalities and authorities in heavens. Made known through the Church, you and I, the Priests, Bishops and the Pope.
