For through him we both have access by one Spirit unto the Father.
Read Chapter 2
Gaius Marius Victorinus
Both Jews and Gentiles “have access to the Father” through Christ himself. But how? “In one Spirit.” For the Spirit, who is one with Christ, enters into us when we believe in Christ. We then feel God’s presence, know God and worship God. Thus we come to the Father in that same Spirit through Christ. No one, whether Jew or Gentile, comes to the Father except through Christ. . ...
However, it should not be thought possible to achieve perfect and complete reconciliation in this world…. The making of the new person in Christ will be fully consummated when earthly and heavenly things have been reconciled, when we come to the Father in one Spirit and with one affection and understanding. . ...
“We both” means not less to one and more to another but having access by a single grace. For he has dispelled the wrath through death and made us all beloved to the Father through one Spirit. Note that in here means “through.” .
