When F.H. Elpis argued that in baptism, believers are united with the second person of the Godhead (i.e. Jesus), yet confirmation is the necessary second-stage for receiving the indwelling presence of the third person (i.e. the Spirit), G.W.H. Lampe ably retorts:
This is wholly false. The Church was not told to await the Paraclete after being already united with the Second Person of the Trinity; the disciples were promised the coming of the Paraclete to be the mediator to them of the glorified Christ: to make them Christian believers, united with the Lord and receiving new life through him. The idea that we can be Christians, united by faith with Christ, and yet be without the indwelling of the Spirit, is a basic Trinitarian error, resting on a tritheistic theology.
