Heidelberg Catechism 26.70

Chapter 26 — Lord's Day 26

Section 70. Q. 70: What does it mean to be washed with Christ's blood and Spirit? A. To be washed with Christ's blood means that God, by grace, has forgiven my sins because of Christ's blood poured out for me in his sacrifice on the cross. To be washed with Christ's Spirit means that the Holy Spirit has renewed me and set me apart to be a member of Christ so that more and more I become dead to sin and increasingly live a holy and blameless life.
