This is a very interesting aside; the digressions in St. Paul, as in Plato, are sometimes more attractive than the arguments. It shows us, for one thing, the freedom of the Christian faith. Those who have received the Gospel have all the responsibilities of mature men; they have come to their majority as spiritual beings; they are not, in their character and standing as Christians, subject to arbitrary and irresponsible interference on the part of others. Paul himself was the great preacher of this spiritual emancipation: he gloried in the liberty with which Christ made men free. For him the days of bondage were over; there was no subjection for the Christian to any custom or tradition of men, no enslavement of his conscience to the judgment or the will of others, no coercion of the spirit except by itself. He had great confidence in this Gospel and in its power to produce generous and beautiful characters. That it was capable of perversion also he knew very well. It was open to the infusion of self-will; in the intoxication of freedom from arbitrary and unspiritual restraint, men might forget that the believer was bound to be a law to himself, that he was free, not in lawless self-will, but only in the Lord. Nevertheless, the principle of freedom was too sacred to be tampered with; it was necessary both for the education of the conscience and for the enrichment of spiritual life with the most various and independent types of goodness; and the Apostle took all the risks, and all the inconveniences even, rather than limit it in the least.
