John Calvin on Acts 26:4-5

4. My life which I have led. He doth not as yet enter into the state of the cause; but because he was wrongfully accused and burdened with many crimes, lest king Agrippa should envy the cause “Causae sit infensus,” be prejudiced against the cause. through hatred of the person, he doth first avouch his innocency. For we know that when a sinister suspicion hath once possessed the minds of men, all their senses are so shut up that they can admit nothing. Therefore, Paul doth first drive away the clouds of an evil opinion which were gathered of false reports, that he may be heard of pure and well purged ears. By this we see that Paul was enforced by the necessity of the cause to commend his life which he had led before. But he standeth not long upon that point, but passeth over straightway unto the resurrection of the dead, when he saith that he is a Pharisee. And I think that that is called the most strait sect, not in respect of holiness of life, but because there was in it more natural sincerity of doctrine, and greater learning. For they did boast that they knew the secret meaning of the Scripture. And surely forasmuch as the Sadducees did vaunt that they did stick to the letter, they fell into filthy and gross ignorance after they had darkened the light of the Scripture. The Essenes, contenting themselves with an austere and strait kind of life, did not greatly care for doctrine. Neither doth that any whit hinder, because Christ inveigheth principally against the Pharisees, as being the worst corrupters of the Scripture (Matthew 23:13). For seeing they did challenge to themselves authority to interpret the Scripture according to the hidden and secret meaning, hence came that boldness to change and innovate, wherewith the Lord is displeased. But Paul doth not touch those inventions which they had rashly invented, and which they urged with tyrannous rigor. For it was his purpose to speak only of the resurrection of the dead. For though they had corrupted the law in many points, yet it was meet that the authority of that sect should be of more estimation in defending the sound and true faith, than of the other, which were departed farther from natural purity. Moreover, Paul speaketh only of the common judgment, which did respect the color of more subtile knowledge.
