The answer
In his writings, St. Clement of Rome speaks of the military command structure of the Roman army not just as a metaphor, but as one who endorses and accepts it.921 He shows that some Christians served in the army as though they were in the army of God and obeyed military orders. They occupied various ranks and saw the army as an expression of the need we all have for each other, whether big or small; and of the need to live out the spirit of obedience more generally.922
