The Missing Block
What did the Fall take away, and what remained? Students remove the “original grace” block from a tower and watch the gifts above it slide away, while human nature and freedom stay standing. Then the class discusses where the analogy stops working.

About the ministry
One conversation at a time.
Analogy Apologetics is the teaching work of Deacon Gerald Robinson. Its aim is to help Catholics and other Christians examine difficult questions with Scripture, logic, and familiar examples.
The book Analogy Apologetics expands on this approach. The videos make individual questions easier to share with a class, small group, or friend.
