The Roman military was one of the most formidable fighting forces in the ancient world. They routinely faced and defeated larger opponents because of their unique tactical approach to warfare: they never fought alone. The shield (scutum) allowed Roman soldiers to fight together as a unit, and that’s why Paul connects the shield with the concept of faithfulness.

By the end of this episode, you’ll learn that it’s impossible to stand firm against evil if we’re not standing with each other.
