by the event, mark the certainty of these truths and, therefore,
the divinity of Christ. In Him, then, and through Him, we know God. Apart
from Him, and without the Scripture, without original sin, without a
necessary mediator promised and come, we cannot absolutely prove God, nor
teach right doctrine and right morality. But through Jesus Christ, and in
Jesus Christ, we prove God, and teach morality and doctrine. Jesus Christ
is, then, the true God of men.

But we know at the same time our wretchedness; for this God is none other
than the Saviour of our wretchedness. So we can only know God well by
knowing our iniquities. Therefore those who have known God, without knowing
their wretchedness, have not glorified Him, but have glorified themselves.
Quia... non cognovit per sapientiam... placuit Deo per stultitiam
praedicationis salvos facere.92

548. Not only do we know God by Jesus Christ alone, but we know ourselves
only by Jesus Christ. We know life and death only through Jesus Christ.
Apart from Jesus Christ, we do not know what is our life, nor our death, nor
God, nor ourselves.
