“Paul and Timothy, bond-servants of Christ Jesus, to all the saints in Christ Jesus who are in Philippi, including the overseers and deacons” (Philippians 1:1).
Federal Visionists love this verse because they think that being in Christ Jesus makes someone a saint. They argue that we are first united with Christ, and then, we are justified with Christ because of our union with him. Union with Christ is the ticket to justification. We are in Christ and then declared holy or “saints.” Thus, we are saints in Christ, according to Federal Visionists.
However, nothing could be further from the truth. The Reformed faith has always prized justification as the first and most important part of salvation. We are justified by faith alone, receiving both the forgiveness of our sins and the transfer of the righteousness of Jesus Christ.
Only when we have been justified can we be united to Christ. Justification is the ticket to union with Christ. We become holy or “saints” when we are justified, not when we are united to Christ. Thus, we are saints apart from Christ.
