Shorter CatechismQ 44. What doth the preface to the ten commandments teach us?A. The preface to the Ten Commandments teacheth us, that because God is the Lord, and our God, and Redeemer, therefore we are bound to keep all his commandments.1Luke 1:74-75 that we, being delivered from the hand of our enemies, might serve him without fear, in holiness and righteousness before him all our days. 1 Peter 1:14-19 As obedient children, do not be conformed to the passions of your former ignorance, but as he who called you is holy, you also be holy in all your conduct, since it is written, “You shall be holy, for I am holy.” And if you call on him as Father who judges impartially according to each one's deeds, conduct yourselves with fear throughout the time of your exile, knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot.
