Certainly his early acquaintance with the Greek language and with the life of the Greeks did not remain without influence in forming him as a teacher of the Greeks, or Gentiles.
Yet the few passages from Greek poets in his Athenian speech and in his epistles do not prove that he owed his acquaintance with Greek literature to his education. In 1 Cor. 15:33 he quotes Menander. In Tit. 1:12 he quotes Epimenides. In Acts 17:28 he quotes Aratus.
The first two sayings may have circulated among the people as proverbs. The last is noteworthy for its exactness. Even γάρ is retained: τού γάρ καί γένος έσμέν.
But Aratus was a Cilician by birth, and therefore Paul's countryman. Consequently his poems could have been known to Paul even from school.
Moreover, the apostle himself says that he was educated not in Tarsus, but in Jerusalem (Acts 22:3, άνατεϑραμμένος). After rabbinic education, a zealous Pharisee such as Paul was before his conversion would not have allowed himself to enter such close communion with Gentiles as to study in their academy.
His father, a Pharisee, evidently intended him for the rabbinate. For this reason he was sent to Jerusalem, so that in a Pharisaic school he might become a learned interpreter of Scripture and tradition.
He was educated under Gamaliel, a teacher of the Law from the Pharisaic sect, who, according to Acts 5:34, was honored by all the people. In agreement with this, the Talmud says: From the time Gamaliel died, the glory of the Law also ceased.
Education in these schools consisted in the interpretation of Holy Scripture. Josephus writes that the Jews place all wisdom in this: first, clearly to understand their laws, τά νόμιμα σαφώς έπιστάμευοι; and second, to interpret the power of the sacred books, τήν τών ίερών γραμμάτων δύναμιν έρμηνεύσαί.
According to the Talmud, in Pirke Avoth, ch. 5, 521, the study of the Law began at five years old. At ten began the study of the Mishnah. From thirteen, the youth was already obligated to the strict fulfillment of the Law.
Paul's obligatory study of the Law can be seen from the many passages from Scripture cited in his epistles. Up to fifty passages are cited from memory, that is, without exactly retaining the words of the translation.
Paul's teacher was distinguished by moderation in his view of those who thought differently (Acts 5:34). He was even acquainted with Greek literature.
It is written in the Talmud that he allowed himself to go even into pagan baths adorned with statues of gods. When this aroused astonishment among pagans, Gamaliel answered: the bath was built before the statues.
The bath was not made for the goddess, Venus, but the goddess was placed for the adornment of the bath. Such freedom of spirit could have had a favorable influence on his disciples.
But a young man with a fiery and powerful soul, such as Paul was, would take up nothing except with all ardor. His heart was already inclined toward the most immoderate zeal, and Pharisaism gave much food to such a direction.
From the personal qualities of his character, as well as from his own testimonies, we may conclude that he strove to surpass all his contemporaries in legal righteousness, as fervent Pharisees understood it.
This too was not without the intention of Providence. The more zealously he strove for holiness, the more he had to struggle with the unruly impulses of his fiery and powerful nature.
Thus he had more occasions to prove that there is evil in man which cannot be tamed by the bridle of the Law alone. A man may know the good, yet not always be able to do the good.
Even with a good disposition, he is involuntarily carried from good to evil by the power of impulses opposed to God. Paul surely would never have described such a state so vividly and exactly in Romans ch. 7 if he had not known it by his own experience.
It was also very important for Paul that he came to Christianity from such a sect. In it every precaution was used, and every barrier was erected against the power of desires and passions.
They tried by every means to compel themselves toward the good. Having tested all these measures on himself and learned their weakness, he could speak from his own experience.
As the representative of all men with zealous moral aspirations, he could testify how deeply the sense of the need for redemption lies in human nature. After this, again from his own experience, he could define the relation between inner freedom flowing from faith in redemption and bondage under the Law.
Although Paul was a faithful and zealous disciple of Gamaliel, one cannot conclude from this that Gamaliel's spirit of moderation toward Christianity passed over into him.
A disciple, especially one with such a strong and original spirit, submits to the spiritual influence of his teacher only to the degree that it corresponds to his own disposition of spirit.
The inflexibility of his character, the fire of his nature, and the fire of youth made him a strong zealot, inclined to persecution, against everything that contradicted the system he regarded as holy.
