I'm a bit late getting started but I'd like to post the weekly Heidelberg Catechism questions with accompanying Scripture. I've wanted to work through this catechism, at least read through and meditate on it weekly, for some time now so, I may as well get started and post the readings here. Without further delay, here we go...
Lord's Day 6
Scripture Reading Psalm 110, Isaiah 53
Question 16. Why must the mediator be truly human and perfectly righteous?
Answer. God's justice demands that a human being must pay for human sin; but a sinful human could never pay for others.
Question 17. Why must the mediator also be truly God?
Answer. So that the mediator, by the power of divinity, might bear the weight of God's wrath as a human being, and earn for us and restore to us righteousness and life.
Question 18. Who is this mediator true God and at the same time truly human and perfectly righteous?
Answer. Our Lord Jesus Christ, who was given to redeem us completely and to make us right with God.
Question 19. How do you come to know this?
Answer. The holy gospel tells me. God began to reveal the gospel already in Paradise; later, God proclaimed it by the holy patriarchs and prophets and portrayed it by the sacrifices and other ceremonies of the law and, finally, fulfilled it through God's own dear Son.
Let this be a reminder to us all that the final and ultimate atonement was made by Jesus Christ, seed of the woman.
An inexpensive book worth investing in is Williamson's The Heidleberg Catechism, A Study Guide. Cheap and easy to read yet worth the mental investment to work through this catechism.
