Q 69 What is the communion in grace which the members of the invisible church have with Christ?

A.
The communion in grace which the members of the invisible church have with Christ, is their partaking of the virtue of his mediation, in their justification,[283] adoption,[284] sanctification, and whatever else, in this life, manifests their union with him.[285]

[283] Romans 8:30. Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.

[284] Ephesians 1:5. Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will.

[285] 1 Corinthians 1:30. But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption.
