By saying that he was so devoted to the law, Saint Paul left this thought with them: such a lover of the law abandoned it, and this cannot be without cause.
‘I advanced in Judaism.’ This is not the same as the earlier phrase, ‘my way of life in Judaism.’ There only outward belonging to Judaism is signified. Here his inner relation to it is indicated.
Judaism means the faith, morals, and customs of every kind by which the Jews were distinguished.
Advancement in it, of course, consisted in studying all this, following it, being devoted to it, and forming himself according to Jewish principles. Thus it was obvious to all that he was a true Jew in soul and body.
Seeing him as such, others undoubtedly treated him with honor and nourished great hopes for him.
In this respect, ‘I advanced’ means: I rose upward, and had already become one of the active men in whom the authorities themselves placed much trust.
‘Beyond many of my contemporaries.’ I was not among the ordinary members of our younger generation. I surpassed many, or all of them.
It is as though he says: I had many contemporaries, but I surpassed them all both in knowledge of Judaism and in zeal for it.
Perhaps Saint Paul wished to express something more than this. In every age the younger generation presents zealots for what belongs to the homeland, for what is regarded as its distinction and adorns it.
Saint Paul places himself among them and assures us that he was more zealous for Judaism than all such zealots.
He does not compare himself with the indifferent and sluggish, but with the living and active. He says that he surpassed all such men.
This was precisely what he needed to set before the Galatians. Then his estrangement from Judaism would appear all the more striking, and his change would point more decisively to the participation of a supernatural power.
‘In my nation’ does not mean the Pharisaic sect, but the Jewish nation, among the Jews in general.
‘Being exceedingly zealous for the traditions of my fathers.’ ‘Exceedingly’ is not the same as the earlier ‘beyond measure.’ There excess is signified. Here only superiority over others is meant.
In Greek, there it is kath' hyperbolen, while here it is perissoteros. He not only advanced in Judaism more than all, but also surpassed all in zeal for it.
He advanced only beyond his contemporaries. But concerning zeal he hints that he was more zealous than all, not only than his contemporaries, but also than those older than he.
From the Acts of the Apostles it is indeed evident that he was the mover and inflamer of the persecution.
By ‘ancestral traditions’ Saint Paul embraces the whole totality of views, rules of life, morals, and customs that then constituted Judaism. He means all Judaism as it had been formed up to his time and handed down from elders to the younger.
At the same time, he gives us to understand that in this formation the guide and determiner was not so much Scripture as the tradition of the elders.
Consequently, distorted Judaism is meant. In it the chief concept of Judaism was distorted, namely, that Judaism was supposedly an eternal and unchangeable religion, obligatory for all.
Much had also been introduced into life that was extremely constricting yet useless. Nevertheless, it was considered a condition of pleasing God and of salvation.
Blessed Jerome writes: ‘Saint Paul acted wisely by inserting into his narrative the indication that he served not so much the law of God as the traditions of the fathers.
According to these traditions they taught doctrines and commandments of men (see Mt 15; Mk 7), and rejected the law of God in order to uphold their traditions.
In this same sense he said above that he advanced not in the law, but in Judaism.’
The same thought is found in blessed Augustine: ‘If Paul, being zealous for his ancestral traditions, persecuted the Church of God, then it is evident that his ancestral traditions are contrary to the Church of God.
But the law cannot be such. It is not responsible for the persecution raised among the Jews against the Church.
The guilty ones are the fleshly Jews. Even what they received as spiritual they understood fleshly, and in addition they added much of their own.
Thus, as the Lord says, they destroyed the commandment of God for the sake of their traditions (see Mt 15:3).’
The holy Fathers perceived what impression this simple narrative must have produced in the souls of the Galatians. In this respect they draw various inferences, corresponding to the aim Saint Paul had in recalling his former life and his conversion.
He persecuted the faith, and now he spreads it. He was wholeheartedly devoted to Judaism, with great hopes for himself, and now he has turned away from it, undergoing deprivations of every kind.
Such a turn in life is unthinkable without instruction from above.
Jerome writes: ‘It is marvelous that not some slight persecutor, but one who surpassed the others in persecution, turned to the faith.’
Oecumenius continues: ‘Since the Galatians did not know of the revelation from Christ that came to him, the Apostle wishes, by pointing out that he was formerly a persecutor and then suddenly changed, to instill in them this thought.
If there had not been some divine revelation to him, he would not have changed so quickly. Thus, being convinced that he is Christ’s disciple, they should no longer despise him.’
Saint John of Damascus draws the same thought from Saint Paul’s sudden change and adds: ‘Another thing is also suggested here covertly, namely that one should no longer hold to the works of the law.
For if one who showed such zeal for the law abandoned it and passed over to the way of salvation by faith, it is clear that he abandoned it from the conviction that it could not lead to perfection.
If such a zealot for the law abandons it, much more should those who have directly fled to the faith not follow this weak law.’
Ambrosiaster carries through the same thought: ‘I, he says, was more zealous for the law than all. But when, after revelation, I learned that it had already lost its force, I wholly gave myself to faith and grace.
From this it followed: if this Israelite, a disciple of the famous Gamaliel, connected with all the best men among the Jews, abandoned the law, much more should those who were outside the law not subject themselves to it.
If he rejoices that he has come out from under the yoke of bondage, why should they bind their freedom with the bonds of the law?’
Oecumenius again understands Paul’s advancement in Judaism in a worldly sense. That is, he became more and more honorable in the eyes of the Jews.
He speaks in Saint Paul’s person: ‘What then is the reason that I suddenly raised war against those who honored and loved me? Nothing else but the appearing of Christ.’
Saint Chrysostom directs everything chiefly toward showing in Saint Paul a zeal for God and love for truth, detached from every earthly calculation.
These are his thoughts on verse 14: ‘Lest you think that he acted thus, that is, persecuted the Church, in anger and malice, he adds that he did all this from zeal, though in ignorance.
He persecuted not from vainglory and not from enmity, but because he was zealous for his ancestral traditions.
These words mean the following. If what I did against the Church I did not do for man, but from divine zeal, though mistaken, yet still from zeal, then how can I now contend for the Church and know the truth from vainglory?
If, during my error, such a passion did not possess me, but zeal for God moved me to my former course of action, then much more, after I have come to know the truth, is it unjust to suspect vainglory in me.
As soon as I turned to the dogmas of Christ’s Church and renounced all Jewish errors, I showed even greater zeal here than there.
This proves that I truly changed and am seized by divine zeal. If not this, tell me, what else disposed me to such a change?
What made me exchange honor for reproach, rest for dangers, and safety for sufferings? Nothing else but love for the truth.’
