Galatians 5:18

But if ye are led of the Spirit, ye are not under the law. This anticipates a possible objection of the Galatians that they had apparently only exchanged one yoke for another heavier one, under which they had constantly to fight a tedious and irksome battle. The Apostle replies to this that if they were led by the Spirit they were not the slaves of concupiscence but its masters, and so were not under the law, inasmuch as they kept its provisions not from fear, but by spontaneously doing what it bade, and restraining the motions of concupiscence forbidden by it.

The Galatians were not, says S. Paul, under the law as a compelling force, still less under it as accusing and condemning, but they were under it as binding the conscience. Even so, however, they kept the law of their own accord, and so might be said to be outside the law, or above the law; not under it, but rather under the Spirit. This is why, after enumerating the fruits of the Spirit, he adds, Against such there is no law.
