Episode Summary: The Westminster Shorter Catechism with Sinclair Ferguson

Question & Answer 51 – December 12, 2025

Episode Overview

In this short episode, Sinclair Ferguson addresses Question 51 of the Westminster Shorter Catechism: "What is forbidden in the second commandment?" The focus is on understanding what the second commandment prohibits, particularly the worship of God through images or in any manner not clearly prescribed in Scripture. Ferguson makes the essential point that Christian spiritual growth begins by digesting foundational biblical truths, and obedience in worship is at the heart of that foundation.

Key Discussion Points & Insights

1. The Second Commandment’s Prohibition

• Ferguson recites the catechism's answer:
  “The second commandment forbiddeth the worshipping of God by images or any other way not appointed in his word.” [00:02]
• Emphasizes that the commandment speaks not only to what is forbidden (making/worshipping images) but any form of worship that God has not appointed.
  • This covers both the physical making and use of images in worship, and also more subtle deviations from God's instructions in other ways.

2. The Principle Behind the Prohibition

• Ferguson explains the difference between the “regulative principle” (only doing in worship what God commands) and more permissive approaches (adding practices God has not commanded).
• The heart of the commandment is that, "Worship must be shaped by God’s own revealed will" rather than human innovation.

3. The Christian's Call to Scriptural Obedience in Worship

• Urges pastors, parents, and teachers to guide others into a worship that is biblical, avoiding not just obvious errors (like idols) but also creativity that disregards God’s Word.
• Underlines that true spiritual nourishment—moving from “milk” to “meat”—begins with obedience at this basic level.

Notable Quotes & Memorable Moments

• Sinclair Ferguson (00:05):
  "The second commandment is not just saying, ‘Don’t make images for worship.’ It’s telling us that in worship, we’re not free to invent. We are to listen to what God has said in his Word, and do only that."

• Sinclair Ferguson (00:20):
  "Helping others enjoy the 'solid food' of Scripture means teaching them to reverence what God commands, even in the way we worship."
