{3} But this I confess unto thee, that after the way which they call {i} heresy, so worship I the God of my fathers, believing all things which are written in the law and in the prophets:

(3) Paul proceeds in the case of religion from a conjectural state to a practical state, not only admitting of the religion which he was accused of, but also proving it to be true, to be heavenly and from God, and to be the oldest of all religions.

(i) Here this word heresy or sect is taken in a good sense.

People's New Testament

24:14 But this I confess. Ac 24:14-16 are in answer to the second charge, that he is a ringleader of the sect of the Nazarenes (Ac 24:5). He confesses that he worships God after that Way they call a sect (Revised Version). Yet he is a true Jew,

believing all things which are written in the law and in the prophets. In becoming a Christian, he had not, therefore, as they asserted, apostatized from the faith of his fathers.

Wesley's Notes

24:14 After the way which they call heresy - This appellation St. Paul corrects. Not that it was then an odious word; but it was not honourable enough. A party or sect (so that word signifies) is formed by men. This way was prescribed by God. The apostle had now said what was sufficient for his defence; but having a fair occasion, he makes an ingenuous confession of his faith in this verse , his hope in the next, his love in the 17th. Acts 24:14,15,17 So worship I the God of my fathers - This was a very proper plea before a Roman magistrate; as it proved that he was under the protection of the Roman laws, since the Jews were so: whereas had he introduced the worship of new gods he would have forfeited that protection. Believing all things which are written - Concerning the Messiah.

Jamieson-Fausset-Brown Bible Commentary

14, 15. But this I confess to thee-in which Felix would see no crime.

that after the way they call heresy-literally, and better, "a sect."

so worship I the God of my fathers-the ancestral God. Two arguments are contained here: (1) Our nation is divided into what they call sects-the sect of the Pharisees, and that of the Sadducees-all the difference between them and me is, that I belong to neither of these, but to another sect, or religious section of the nation, which from its Head they call Nazarenes: for this reason, and this alone, am I hated. (2) The Roman law allows every nation to worship its own deities; I claim protection under that law, worshipping the God of my ancestors, even as they, only of a different sect of the common religion.

believing all, &c.-Here, disowning all opinions at variance with the Old Testament Scriptures, he challenges for the Gospel which he preached the authority of the God of their fathers. So much for the charge of heresy.

Matthew Henry's Concise Commentary

24:10-21 Paul gives a just account of himself, which clears him from crime, and likewise shows the true reason of the violence against him. Let us never be driven from any good way by its having an ill name. It is very comfortable, in worshipping God, to look to him as the God of our fathers, and to set up no other rule of faith or practice but the Scriptures. This shows there will be a resurrection to a final judgment. Prophets and their doctrines were to be tried by their fruits. Paul's aim was to have a conscience void of offence. His care and endeavour was to abstain from many things, and to abound in the exercises of religion at all times; both towards God. and towards man. If blamed for being more earnest in the things of God than our neighbours, what is our reply? Do we shrink from the accusation? How many in the world would rather be accused of any weakness, nay, even of wickedness, than of an earnest, fervent feeling of love to the Lord Jesus Christ, and of devotedness to his service! Can such think that He will confess them when he comes in his glory, and before the angels of God? If there is any sight pleasing to the God of our salvation, and a sight at which the angels rejoice, it is, to behold a devoted follower of the Lord, here upon earth, acknowledging that he is guilty, if it be a crime, of loving the Lord who died for him, with all his heart, and soul, and mind, and strength. And that he will not in silence see God's word despised, or hear his name profaned; he will rather risk the ridicule and the hatred of the world, than one frown from that gracious Being whose love is better than life.
