Of the same nature are the precepts which Paul gives, in Romans xiii [Rom. 13:1 ff.] and Titus iii [Tit. 3:1], that Christians should be subject to the powers that be, and be ready to do every good work, not that they shall in this way be justified, since they already are righteous through faith, but that in the liberty of the Spirit they shall by so doing serve others and the powers themselves, and obey their will freely and out of love. Of this nature should be the works of all colleges, monasteries and priests. Each one should do the works of his profession and position, not that by them he may strive after righteousness, but that through them he may keep under his body, be an example to others, who also need to keep under their bodies, and finally that by such works he may submit his will to that of others in the freedom of love. But very great care must always be taken that no man in a false confidence imagine that by such works he will be justified, or acquire merit or be saved; for this is the work of faith alone, as I have repeatedly said. [Sidenote: Church Precepts] Any one knowing this could easily and without danger find his way among those numberless mandates and precepts of pope, bishops, monasteries, churches, princes and magistrates, upon which some ignorant pastors insist as if they were necessary to righteousness and salvation, calling them "precepts of the Church," although they are nothing of the kind. For a Christian, as a free man, will say, "I will fast, pray, do this and that as men command, not because it is necessary to my righteousness or salvation; but that I may show due respect to the pope, the bishop, the community, some magistrate or my neighbor, and give them an example, I will do and suffer all things, just as Christ did and suffered far more for me, although He needed nothing of it all or Himself, and was made under the law for my sake, although He was not under the law." And although tyrants do violence or injustice in making their demands, yet it will do no harm, so long as they demand nothing contrary to God. From what has been said, every one can pass a safe judgment on all works and laws and make a trustworthy distinction between them, and know who are the blind and ignorant pastors and who are the good and true. For any work that is not done solely for the purpose of keeping under the body or of serving one's neighbor, so long as he asks nothing contrary to God, is not good nor Christian. And for this reason I mightily fear that few or no colleges, monasteries, altars and offices of the Church are really Christian in our day: no, nor the special fasts and prayers on certain saints' days[16] either. I fear, I say, that in all these we seek only our own profit, thinking that through them our sins are purged away and that we ind salvation in them. In this way Christian liberty perishes altogether. And this comes from our ignorance of Christian faith and of liberty. [Sidenote: Ignorance of Liberty]
