The Scriptures profess to lead us to God. Whatever is necessary to that end they must teach us. If any supplementary rule, as tradition, is necessary to that end, they must refer us to it. "Incompleteness here would be falsehood." But while one sacred writer constantly refers us to the writings of another, not one of them ever intimates to us either the necessity or the existence of any other rule.—John xx. 31; 2 Tim. iii. 15–17.
9. By what other arguments may this principle be proved?
As the Scriptures profess to be a rule complete for its end, so they have always been practically found to be such by the true spiritual people of God in all ages. They teach a complete and harmonious system of doctrine. They furnish all necessary principles for the government of the private lives of Christians, in every relation, for the public worship of God, and for the administration of the affairs of his kingdom; and they repel all pretended traditions and priestly innovations.
10. In what sense do Protestants affirm and Romanists deny the 'perspicuity of Scripture?
Protestants do not affirm that the doctrines revealed in the Scriptures are level to man's powers of understanding. Many of them are confessedly beyond all understanding. Nor do they affirm that every part of Scripture can be certainly and perspicuously expounded, many of the prophesies being perfectly enigmatical until explained by the event. But they do affirm that every essential article of faith and rule of practice is clearly revealed in Scripture, or may certainly be deduced therefrom. This much the least instructed Christian may learn at once; while, on the other hand, it is true, that with the advance of historical and critical knowledge, and by means of controversies, the Christian church is constantly making progress in the accurate interpretation of Scripture, and in the comprehension in its integrity of the system therein taught. Protestants affirm and Romanists deny that private and unlearned Christians may safely be allowed to interpret Scripture for themselves.
11. How can the perspicuity of Scripture be proved from the fact that it is a law and a message?
We saw (question 8) that Scripture is either complete or false, from its own professed design. We now prove its perspicuity upon the same principle. It professes to be (1) a law to be obeyed; (2) a revelation of truth to be believed, to be received by us in both aspects upon the penalty of eternal
