Preface of the Small Catechism

So look to it, you pastors and preachers. Our ministry today is something else than it was under the pope. It has become a serious and saving responsibility. Consequently it now involves much more trouble and labor, danger and trial, and in addition it brings you little of the world's gratitude and rewards. But Christ Himself will be our reward if we labor faithfully. The Father of all grace help us to do just that. To Him be praise and thanks forever through Christ our Lord. Amen.
