If, however, you aare fulfilling the 1royal law according to the Scripture, “bYOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF,” you are doing well. But if you ashow partiality, you are committing sin and are convicted by the 1law as transgressors. For whoever keeps the whole 1law and yet astumbles in one point, he has become bguilty of all. For He who said, “aDO NOT COMMIT ADULTERY,” also said, “bDO NOT COMMIT MURDER.” Now if you do not commit adultery, but do commit murder, you have become a transgressor of the 1law. So speak and so act as those who are to be judged by athe law of liberty. (Jam 2:8-12 NASB)
Owe nothing to anyone except to love one another; for ahe who loves 1his neighbor has fulfilled the law. For this, “aYOU SHALL NOT COMMIT ADULTERY, YOU SHALL NOT MURDER, YOU SHALL NOT STEAL, YOU SHALL NOT COVET,” and if there is any other commandment, it is summed up in this saying, “bYOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.” Love 1does no wrong to a neighbor; therefore alove is the fulfillment of the law. (Rom 13:8-10 NASB)
I don’t want to spend a lot of time on this, but one author is using and responding to another. For James, it looks as if he is saying that the law must be fulfilled in every way. Paul responds with much the same line, but changes it to position love not just as well, but as the perfection.
