Ordo Salutis - Multimedia
"union with Christ... underlies all of soteriology."
Every facet of the application of Christ's work ought to be related to the way in which the Spirit unites us to Christ himself, and viewed directly as issuing from personal fellowship with him. The dominant motif and architectonic principle of the order of salvation should therefore be union with Christ in the Spirit." (Sinclair B. Ferguson, The Holy Spirit, Contours of Christian Theology, IVP, 1996, p. 100)
"The ordo salutis describes the process by which the work of salvation, wrought in Christ, is subjectively realized in the hearts and lives of sinners. It aims at describing in their logical order, and also in their interrelations, the various movements of the Holy Spirit in the application of the work of redemption. The emphasis is not on what man does in appropriating the grace of God, but on what God does in applying it." - Louis Berkhof
