The Lutheran Church knows that the Lord gives his Holy Spirit only through his Word and sacraments, and therefore it recognizes no other effective means than Word and sacrament. …
From its knowledge of human nature it knows that men will sooner open their hearts to the truth when it is gladly but sparingly imparted than when they hear its voice speaking constantly. Therefore it understands how to give people enough of its means but not too much. It does not consider it an insult, nor is it eager to interpret it as an insult, when someone says, “This pastor thinks it is enough if he preaches, catechizes, administers the sacraments, hears confessions, and comforts the sick!” It knows that even the most faithful pastors do not do enough of this. It has little use for multiplying pastoral duties but treasures those which are commanded in the Scriptures and have been recognized since ancient times. To many people it is something novel that a man should not be a jack of many trades but a master of the few precious means, yet this is what the church has always thought. In a word, it accomplishes much through a few means. …
It is enough, and more than enough, if a man just carries out the ancient duties of a pastor. Superfluous and even a hindrance is the officiousness of modern pastors. Here the slogan should be, “Not many, but much.” The poverty of our fathers is richer than the wealth of their opponents. It is through alternating periods of withdrawal and public appearance, stillness and publicity, through persistent use of Word and sacrament, through giving of a quiet but full measure, through modesty and steadfastness that the Lutheran church attains its goals.
It is not concerned with new means of encouraging good works, although they have been highly praised. It does not desire to do its good works the way societies or factories do. It knows that works carried out in the fashion of modern societies easily displace other works, disturb the harmony of manifold good works, and make men one-sided and intemperate. It is afraid that societies which separate from the church and act as if everything depended on them may become organizations of extravagance and intemperance, even though they carry the name “temperance” in their titles. …
The church has various activities, therefore, even though the means through which it performs them and encourages all good things are always the same–Word, sacrament, the holy office of the ministry.
Few means–many good works! That is the way it is with the church.
