Heidelberg Catechism: Lord’s Day 7

Q: 20. Are all men then, as they perished in Adam, saved by Christ?
A: No; only those who are grafted into him, and, receive all his benefits, by a true faith.

Q: 21. What is true faith?
A: True faith is not only a certain knowledge, whereby I hold for truth all that God has revealed to us in his word, but also an assured confidence, which the Holy Spirit works by the gospel in my heart; that not only to others, but to me also, remission of sin, everlasting righteousness and salvation, are freely given by God, merely of grace, only for the sake of Christ’s merits.

Q: 22. What is then necessary for a Christian to believe?
A: All things promised us in the gospel, which the articles of our catholic undoubted Christian faith briefly teach us.

Q: 23. What are these articles?
A: 1. I believe in God the Father, Almighty, Maker of heaven and earth: 2. And in Jesus Christ, his only begotten Son, our Lord: 3. Who was conceived by the Holy Spirit, born of the Virgin Mary: 4. Suffered under Pontius Pilate; was crucified, dead, and buried: He descended into hell: 5. The third day he rose again from the dead: 6. He ascended into heaven, and sits at the right hand of God the Father Almighty: 7. From thence he shall come to judge the quick and the dead: 8. I believe in the Holy Spirit: 9. I believe a holy catholic church: the communion of saints: 10. The forgiveness of sins: 11. The resurrection of the body: 12. And the life everlasting.
