We find in Ephesians 1, 3-14 a blessing, the inner movement of which (such as it comes out from the literary genre, the construction of the text and the vocabulary) raises the question of the relationship between election, filiation and redemption. In presenting Christ not as the Revealer but as the content of Revelation, this blessing shows that Redemption takes all its place in God's design without having to be its foundation. Resuming then the two historic modalities of the Revelation, the blessing lays down the basis of the ecclesiology which will be expounded in the Epistle: the Church is solely defined by the relationship of the believers in Christ, whatever may be their ethnic, cultural and even religious extraction.
