In declining pecuniary remuneration, Paul was acting on his general principle of making himself the servant of all and of living entirely and exclusively for the good of others. "Though I be free from all men, yet have I made myself servant unto all, that I might gain the more." It was from Paul that Luther derived his two propositions which he uttered as the keynote of the resonant blast "on Christian Liberty" with which he stirred all Europe into new life: "A Christian man is the most free lord of all, and subject to none; a Christian man is the most dutiful servant of all, and subject to every one." So Paul's independence of all men was assumed and maintained for the very purpose of making himself the more effectually the servant of all. To the Jew and to those under the Law he became as a Jew, observing the seventh day, circumcising Timothy, abstaining from blood, accommodating himself to all their scruples. To those who were without the Law, and who had been brought up in Greece, he also conformed himself, freely entering into their innocent customs, calling no meats unclean, appealing, not to the law of Moses, but to conscience, to common-sense, to their own poets. "I am made all things to all men, that I might by all means save some"--a course which none but a man of wide sympathy and charity, clear intellect, and thorough integrity can adopt. For Paul was no mere latitudinarian. While accommodating himself to the practice of those around him in all matters of mere outward observance, and which did not touch the essentials of morality and faith, he at the same time held very definite opinions on the chief articles of the Christian creed. No amount of liberality of sentiment can ever induce a thoughtful man to discourage the formation of opinion on all matters of importance. On the contrary, the only escape from mere traditionalism or the tyranny of authority in matters of religion is in individual inquiry and ascertainment of the truth. Free inquiry is the one instrument we possess for the discovery of truth; and by pursuing such inquiry men may be expected to come to some agreement in religious belief, as in other things. No doubt righteousness of life is better than soundness of creed. But is it not possible to have both? It is better to live in the Spirit, to be meek, chaste, temperate, just, loving, than to understand the relation of the Spirit to God and to ourselves; but the human mind can never cease to seek satisfaction: and truth, the more clearly it is seen, will the more effectually nourish righteousness.
