Christians are glad to hear and obey this teaching of love. When others hear about this Christian liberty of ours they at once infer, "If I am free, I may do what I like. If salvation is not a matter of doing why should we do anything for the poor?" In this crude manner they turn the liberty of the spirit into wantonness and licentiousness. We want them to know, however, that if they use their lives and possessions after their own pleasure, if they do not help the poor, if they cheat their fellow-men in business and snatch and scrape by hook and by crook everything they can lay their hands on, we want to tell them that they are not free, no matter how much they think they are, but they are the dirty slaves of the devil, and are seven times worse than they ever were as the slaves of the Pope.
As for us, we are obliged to preach the Gospel which offers to all men liberty from the Law, sin, death, and God's wrath. We have no right to conceal or revoke this liberty proclaimed by the Gospel. And so we cannot do anything with the swine who dive headlong into the filth of licentiousness. We do what we can, we diligently admonish them to love and to help their fellow-men. If our admonitions bear no fruit, we leave them to God, who will in His own good time take care of these disrespecters of His goodness. In the meanwhile we comfort ourselves with the thought that our labors are not lost upon the true believers. They appreciate this spiritual liberty and stand ready to serve others in love and, though their number is small, the satisfaction they give us far outweighs the discouragement which we receive at the hands of the large number of those who misuse this liberty.
Paul cannot possibly be misunderstood for he says: "Brethren, ye have been called unto liberty." In order that nobody might mistake the liberty of which he speaks for the liberty of the flesh, the Apostle adds the explanatory note, "only use not liberty for an occasion to the flesh, but by love serve one another." Paul now explains at the hand of the Ten Commandments what it means to serve one another in love.
VERSE 14. For all the law is fulfilled in one word, even in this, thou shalt love thy neighbour as thyself.
It is customary with Paul to lay the doctrinal foundation first and then to build on it the gold, silver, and gems of good deeds. Now there is no other foundation than Jesus Christ. Upon this foundation the Apostle erects the structure of good works which he defines in this one sentence: "Thou shalt love thy neighbour as thyself."
In adding such precepts of love the Apostle embarrasses the false apostles very much, as if he were saying to the Galatians: "I have described to you what spiritual life is. Now I will also teach you what truly good works are.
I am doing this in order that you may understand that the silly ceremonies of which the false apostles make so much are far inferior to the works of Christian love." This is the hall-mark of all false teachers, that they not only pervert the pure doctrine but also fail in doing good. Their foundation vitiated, they can only build wood, hay, and stubble. Oddly enough, the false apostles who were such earnest champions of good works never required the work of charity, such as Christian love and the practical charity of a helpful tongue, hand, and heart. Their only requirement was that circumcision, days, months, years, and times should be observed. They could not think of any other good works.
The Apostle exhorts all Christians to practice good works after they have embraced the pure doctrine of faith, because even though they have been justified they still have the old flesh to refrain them from doing good.
Therefore it becomes necessary that sincere preachers cultivate the doctrine of good works as diligently as the doctrine of faith, for Satan is a deadly enemy of both. Nevertheless faith must come first because without faith it is impossible to know what a God-pleasing deed is.
Let nobody think that he knows all about this commandment, "Thou shalt love thy neighbour as thyself." It sounds short and easy, but show me the man who can teach, learn, and do this commandment perfectly. None of us heed, or urge, or practice this commandment properly. Though the conscience hurts when we fail to fulfill this commandment in every respect we are not overwhelmed by our failure to bear our neighbor sincere and brotherly love.
The words, "for all the law is fulfilled in one word," entail a criticism of the Galatians. "You are so taken up by your superstitions and ceremonies that serve no good purpose, that you neglect the most important thing, love." St. Jerome says: "We wear our bodies out with watching, fasting, and labor and neglect charity, the queen of all good works." Look at the monks, who meticulously fast, watch, etc. To skip the least requirement of their order would be a crime of the first magnitude. At the same time they blithely ignored the duties of charity and hated each other to death. That is no sin, they think.
The Old Testament is replete with examples that indicate how much God prizes charity. When David and his companions had no food with which to still their hunger they ate the showbread which lay-people were forbidden to eat. Christ's disciples broke the Sabbath law when they plucked the ears of corn. Christ himself broke the Sabbath (as the Jews claimed) by healing the sick on the Sabbath. These incidents indicate that love ought to be given consideration above all laws and ceremonies.
VERSE 14. For all the Law is fulfilled in one word.
