But, because the
remission of sins is communicated through the Word, which, as
has been frequently said, was entrusted by our Lord to the
Church and her ministers, yea, unto all Christians, that it
should be preached, it follows that this remission of sin must
be believed, and that there is no way of obtaining it, except
by faith. The doctrine of justification by faith
alone is the very foundation of our creed. The word
of Christ, which He gave to His disciples, can certainly not
be seized with the hands nor by any self-imposed works, such
as fasting, prayers, giving of alms and the like; faith alone
can appropriate it, and the heart alone is the proper
receptacle for it. It is evident and certain that we are
justified only through faith, because remission of sins comes
through the Word, and the Word can be received only by faith.
