Today the Church commemorates the publication of Luther’s Large Catechism in 1529. Read more what is written in this Catechism here:  http://bocl.org?LC+INTRO

Luther writes: “For it needs must be that whoever knows the Ten Commandments perfectly must know all the Scriptures, so that, in all affairs and cases, he can advise, help, comfort, judge, and decide both spiritual and temporal matters, and is qualified to sit in judgment upon all doctrines, estates, spirits, laws, and whatever else is in the world. And what, indeed, is the entire Psalter but thoughts and exercises upon the First Commandment?  Now I know of a truth that such lazy paunches and presumptuous spirits do not understand a single psalm, much less the entire Holy Scriptures; and yet they pretend to know and despise the Catechism, which is a compend and brief summary of all the Holy Scriptures.

Therefore I again implore all Christians, especially pastors and preachers, not to be doctors too soon, and imagine that they know everything (for imagination and cloth unshrunk [and false weights] fall far short of the measure), but that they daily exercise themselves well in these studies and constantly treat them; moreover, that they guard with all care and diligence against the poisonous infection of such security and vain imagination, but steadily keep on reading, teaching, learning, pondering, and meditating, and do not cease until they have made a test and are sure that they have taught the devil to death, and have become more learned than God Himself and all His saints.”
