Galatians 1:23

But they had heard only, That he which persecuted us in times past now preacheth the faith which once he destroyed.

But they had heard only,.... What they knew of the apostle was only by hearsay; they had never seen him, nor heard him preach, nor conversed with him, only had it reported to them;

That he which persecuted us in times past; some few years ago, and not them personally, but such as were of the same faith with them, the church at Jerusalem and the members of it; which he made havoc of, committing men and women to prison, and causing others to flee to strange cities;

now preacheth the faith which once he destroyed; all as in him lay he endeavoured to destroy it, though he could not entirely root it up; he destroyed many of the disciples that held it, and did all he could to discourage others from embracing and professing it; he made use of the strongest arguments he was master of to confute it, and of the secular arm to crush and extirpate it, but now was become a preacher of it: by "faith" is meant not so much the grace of faith, though to show the nature, necessity, and usefulness of faith in Christ, and to direct and encourage sensible sinners, as he did the jailer, to believe in him, was a principal part of his ministry; but rather the doctrine of faith, which is always designed, when it is said, as here, to be preached or to be obeyed, stood fast in and contended for, or to be departed and erred from, to be made shipwreck of and denied. The Gospel is called the word of faith, the mystery of faith, the faith of the Gospel, common faith, most holy faith, the faith once delivered to the saints; it contains things to be believed; it proposes and directs to the great object of faith; and is the means of implanting and increasing that grace, and without which the ministry of it is of no use: it takes in all articles of faith, respecting the divine Being, the unity of God, the trinity of persons in the Godhead, the equal and proper deity of each person, their personal distinctions from each other, the attribution of all divine works, worship and honour to them; it relates to everything concerning man, in his original creation, in his state of innocence and integrity; concerning the fall of Adam, the imputation of his sin to all his posterity, the corruption of human nature, and the impotence of man to all that is spiritually good: it regards all the acts of grace of the Father, Son, and Spirit, in and towards any of the sons of men: it includes all the doctrines of it, as of the free, sovereign, everlasting, and unchangeable love of God; of eternal, personal, and irrespective election of some to grace and glory, by which both are secured; of the everlasting, absolute, unconditional, and sure covenant of grace; of particular redemption by Christ, proceeding on a full satisfaction to divine justice; of justification by the imputed righteousness of Christ; of reconciliation and pardon by his blood; of regeneration and sanctification by the Spirit; of the perseverance of the saints in faith and holiness, the resurrection of the dead, and eternal glory: now this faith, in the several momentous branches of it, the apostle preached, published, declared, spoke out openly and publicly; fully and completely, without dropping, concealing, or keeping back anything; clearly and plainly, without using ambiguous phrases, or words of double meaning, with all faithfulness and integrity, boldness and constancy.
