3 I do not adduce these instances because I have anything in me from which you either can or will learn a lesson, but to show you that your zeal and eagerness to learn— even though you cannot rely on help from me— are in themselves worthy of praise. A mind willing to learn deserves commendation even when it has no teacher. What is of importance to me is not what you find but what you seek to find. Wax is soft and easy to mould even where the hands of craftsman and modeller are wanting to work it.
It is already potentially all that it can be made. The apostle Paul learned the Law of Moses and the prophets at the feet of Gamaliel and was glad that he had done so, for armed with this spiritual armour, he was able to say boldly “the weapons of our warfare are not carnal, but mighty through God to the pulling down of strongholds;” armed with these we war “casting down imaginations and every high thing that exalts itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ; and being in a readiness to revenge all disobedience.” He writes to Timothy who had been trained in the holy writings from a child exhorting him to study them diligently and not to neglect the gift which was given him with the laying on of the hands of the presbytery. To Titus he gives commandment that among a bishop's other virtues (which he briefly describes) he should be careful to seek a knowledge of the scriptures: A bishop, he says, must hold fast “the faithful word as he has been taught that he may be able by sound doctrine both to exhort and to convince the gainsayers.” In fact want of education in a clergyman prevents him from doing good to any one but himself and much as the virtue of his life may build up Christ's church, he does it an injury as great by failing to resist those who are trying to pull it down. The prophet Haggai says— or rather the Lord says it by the mouth of Haggai— “Ask now the priests concerning the law.” For such is the important function of the priesthood to give answers to those who question them concerning the law. And in Deuteronomy we read “Ask your father and he will show you; your elders and they will tell you.” Also in the one hundred and nineteenth psalm “your statutes have been my songs in the house of my pilgrimage.” David too, in the description of the righteous man whom he compares to the tree of life in paradise, among his other excellences speaks of this, “His delight is in the law of the Lord; and in his law does he meditate day and night.” In the close of his most solemn vision Daniel declares that “the righteous shall shine as the stars; and the wise, that is the learned, as the firmament.” You can see, therefore, how great is the difference between righteous ignorance and instructed righteousness. Those who have the first are compared with the stars, those who have the second with the heavens. Yet, according to the exact sense of the Hebrew, both statements may be understood of the learned, for it is to be read in this way:— “They that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars forever and ever.” Why is the apostle Paul called a chosen vessel? Assuredly because he is a repertory of the Law and of the holy scriptures. The learned teaching of our Lord strikes the Pharisees dumb with amazement, and they are filled with astonishment to find that Peter and John know the Law although they have not learned letters. For to these the Holy Ghost immediately suggested what comes to others by daily study and meditation; and, as it is written, they were “taught of God.” The Saviour had only accomplished his twelfth year when the scene in the temple took place; but when he interrogated the elders concerning the Law His wise questions conveyed rather than sought information.
