I believe BECAUSE it's impossible.

The Son of God died; it is by all means to be believed because it is absurd. And he was buried and rose again; the fact is certain, because it is impossible.

The angels as the guardians of men are set over men as instructors and monitors. This shows the relationship that is to exist between them. Man's attitude is to be one of obedience and subjection. He is to follow the lead of the angels, and consequently some reverence is already implied in the very relationship that exists between man and angel.

He is a man, who is to be a man; the fruit is always present in the seed.

Examine then, and see if He be not the dispenser of kingdoms, who is Lord at once of the world which is ruled, and of man himself who rules; if He have not ordained the changes of dynasties, with their appointed seasons, who was before all time, and made the world a body of times; if the rise and the fall of states are not the work of Him, under whose sovereignty the human race once existed without states at all.

It is certain because it is impossible. -Certum est quia impossibile

But now inquiry is being made concerning these issues. First, can any believer enlist in the military? Second, can any soldier, even those of the rank and file or lesser grades who neither engage in pagan sacrifices nor capital punishment, be admitted into the church? No on both counts.
