What was one of the most impactful reforms of the Reformation?

David Eddy explains in this video that before the Reformation, tradition had largely controlled matters of Church and family life. The Reformation resulted in a tearing down of those traditions and customs and a return to the Scriptures as the source of wisdom and truth.

The return to Scripture was the key to much of the Reformation and the same is true for reformation today. God’s Word never changes - it is the rock that withstands time and attacks upon it. His Word is continuously “living and powerful” (Hebrews 4:12).

Matthew 7:24 (NKJV) – “Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock.” 

I believe the most helpful reform is that before the Protestant Reformation, tradition had really taken over the driver's seat in theology and the Reformation said no it's going to be Scripture and is there's lots of different things the Reformation did well some things they didn't do as well as they could have for sure but I think that that was the getting back to scripture as the standard for faith and practice was really the key to that.
