I am a debtor both to the Greeks and to the Barbarians, etc. Those whom he means by the Greeks and the Barbarians, he afterwards explains by adding, both to the wise and to the foolish; which words Erasmus has not rendered amiss by "learned and unlearned," (eruditos et rudes,) but I prefer to retain the very words of Paul. He then takes an argument from his own office, and intimates that it ought not to be ascribed to his arrogance, that he thought himself in a manner capable of teaching the Romans, however much they excelled in learning and wisdom and in the knowledge of things, inasmuch as it had pleased the Lord to make him a debtor even to the wise. [1] Two things are to be here considered -- that the gospel is by a heavenly mandate destined and offered to the wise, in order that the Lord may subject to himself all the wisdom of this world, and make all variety of talents, and every kind of science, and the loftiness of all arts, to give way to the simplicity of his doctrine; and what is more, they are to be reduced to the same rank with the unlearned, and to be made so meek, as to be able to bear those to be their fellow-disciples under their master, Christ, whom they would not have deigned before to take as their scholars; and then that the unlearned are by no means to be driven away from this school, nor are they to flee away from it through groundless fear; for if Paul was indebted to them, being a faithful debtor, he had doubtless discharged what he owed; and thus they will find here what they will be capable of enjoying. All teachers have also a rule here which they are to follow, and that is, modestly and kindly to accommodate themselves to the capacities of the ignorant and unlearned. Hence it will be, that they will be able, with more evenness of mind, to bear with many absurdities and almost innumerable things that may disgust them, by which they might otherwise be overcome. They are, however, to remember, that they are not so indebted to the foolish, as that they are to cherish their folly by immoderate indulgence.

Footnotes

1 - Chalmers paraphrases the text thus -- "I am bound, or I am under obligation, laid upon me by the duties of my office, to preach both to Greeks and Barbarians, both to the wise and the unwise." In modern phraseology, the words may be rendered, "Both to the civilized and to the uncivilized, both to the learned and to the unlearned, am I a debtor." The two last terms are not exactly parallel to the two first, as many unlearned were among the Greeks, or the civilized, as well as among the Barbarians. -- Ed.

I am debtor - This does not mean that they had conferred any favor on him, which bound him to make this return, but that he was under obligation to preach the gospel to all to whom it was possible. This obligation arose from the favor that God had shown him in appointing him to this work. He was specially chosen as a vessel to bear the gospel to the Gentiles Acts 9:15; Romans 11:13, and he did not feel that he had discharged the obligation until he had made the gospel known as far as possible among all the nations of the earth.
To the Greeks - This term properly denotes "those who dwelt in Greece." But as the Greeks were the most polished people of antiquity, the term came to be synonymous with the polished, the refined, the wise, as opposed to barbarians. In this place it doubtless means the same as "the wise," and includes the Romans also, as it cannot be supposed that Paul would designate the Romans as barbarians. Besides, the Romans claimed an origin from Greece, and Dionysius Halicarnassus (book i.) shows that the Italian and Roman people were of Greek descent.
Barbarians - All who were not included under the general name of Greeks. Thus, Ammonius says that "all who were not Greeks were barbarians." This term "barbarian," Βάρβαρος Barbaros, properly denotes one who speaks a foreign language, a foreigner, and the Greeks applied it to all who did not use their tongue; compare 1-Corinthians 14:11, "I shall be unto him that speaketh, a barbarian, etc. that is, I shall speak a language which he cannot understand. The word did not, therefore, of necessity denote any rusticity of manners, or any lack of refinement.
To the wise - To those who esteemed themselves to be wise, or who boasted of their wisdom. The term is synonymous with "the Greeks," who prided themselves much in their wisdom. 1-Corinthians 1:22, "the Greeks seek after wisdom;" compare 1-Corinthians 1:19; 1-Corinthians 3:18-19; 1-Corinthians 4:10; 2-Corinthians 11:19.
Unwise - Those who were regarded as the ignorant and unpolished part of mankind. The expression is equivalent to ours, 'to the learned and the unlearned.' It was an evidence of the proper spirit to be willing to preach the gospel to either. The gospel claims to have power to instruct all mankind, and they who are called to preach it, should be able to instruct those who esteem themselves to be wise, and who are endowed with science, learning, and talent; and they should be willing to labor to enlighten the most obscure, ignorant, and degraded portions of the race. This is the true spirit of the Christian ministry.
So, as much as in me is - As far as opportunity may be offered, and according to my ability.
I am ready - I am prepared to preach among you, and to show the power of the gospel, even in the splendid metropolis of the world. He was not deterred by any fear; nor was he indifferent to their welfare; but he was under the direction of God. and as far as he gave him opportunity, he was ready to make known to them the gospel, as he had done at Antioch, Ephesus, Athens, and Corinth.
This closes the introduction or preface to the Epistle. Having shown his deep interest in their welfare, he proceeds in the next verse to state to them the great doctrines of that gospel which he was desirous of proclaiming to them.

I am a debtor both to the Greeks, and to the barbarians - It has been remarked before that all the nations of the earth, themselves excepted, were termed barbarians by the Greeks. See the origin of the word barbarous in the note on Acts 28:2 (note). The apostle considers himself, by his apostolical office and call, under obligation to preach the Gospel to all people, as far as the providence of God might open his way; for this is implied in the Divine commission: - Go ye into all the world, and preach the Gospel to every creature - to the wise and the unwise; to the learned and cultivated as well as to the unlearned and uncultivated. This evidently appears to be the import of the terms.

I am a debtor both to the Greeks, and to the Barbarians,.... The meaning is, that he was obliged by the call he had from God, the injunction that was laid upon him by him, and the gifts with which he was qualified, to preach the Gospel to all sorts of men; who are here distinguished into Greeks and Barbarians: sometimes by Greeks are meant the Gentiles in general, in opposition to the Jews; see Romans 1:16; but here they design only a part of the Gentiles, the inhabitants of Greece, in opposition to all the world besides; for the Greeks used to call all others that were not of themselves Barbarians (e): or else by Greeks are meant the more cultivated nations of the world, and by Barbarians the ruder and more uncivil parts of it; to which agrees the next division of mankind,
both to the wise and to the unwise. The Gospel was to be preached "to the wise"; such who thought themselves to be so, and were so with respect to human wisdom and knowledge; though it should be despised by them, as it was, and though few of them were called by it, some were, and still are, though not many; and such wisdom there is in the Gospel, as the wisest of men may learn by it, will be entertaining to them, is far beyond their contempt, and what will serve to exercise their talents and abilities, to search into the knowledge of, and rightly to understand; and it must be preached "to the unwise"; for such God has chosen to confound the wise; these he calls by his grace, and reveals his Gospel to, whilst he hides it from the wise and prudent; and there is that in the Gospel which is plain and easy to the weakest mind, enlightened by the Spirit of God.

I am debtor both to the Greeks--cultivated
and to the Barbarians--rude.

To the Greeks and the barbarians - He includes the Romans under the Greeks; so that this division comprises all nations. Both to the wise, and the unwise - For there were unwise even among the Greeks, and wise even among the barbarians. I am a debtor to all - I am bound by my divine mission to preach the gospel to them.
