The preaching of the Word of God is the Word of God.
Wherefore when this Word of God is now preached in the church
by preachers lawfully called, we believe that the very Word of God
is proclaimed, and received by the faithful; and that neither any other
Word of God is to be invented nor is to be expected from heaven:
and that now the Word itself which is preached is to be regarded,
not the minister that preaches; for even if he be evil and a sinner,
nevertheless the Word of God remains still true and good.
