Augustine of Hippo

When all these things have been said and considered, I am unwilling to contend about words, for such contention is profitable for nothing but the subverting of the hearer. But the law is profitable for edification if one uses it lawfully. For the end of the law "is love out of a pure heart, and a good conscience and faith unfeigned." And our Master knew it well, for it was on these two commandments that he hung all the law and the prophets.
