"I marvel that ye are so soon removed from him that called you into the grace of God unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be ACCURSED. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be ACCURSED. For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
But I certify you, brethren, that the gospel which was preached of me is NOT AFTER MAN. For I neither RECEIVED IT OF MAN, neither was I TAUGHT IT , but by THE REVELATION OF JESUS CHRIST."
So what was the Gospel of Christ that Paul received by DIRECT REVELATION FROM THE RISEN CHRIST?
"Moreover, brethren, I declare unto you THE GOSPEL which I PREACHED unto you, which also YE HAVE RECEIVED, and wherein YE STAND, by which also YE ARE SAVED, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that CHRIST DIED FOR OUR SINS according to the scriptures, and that HE WAS BURIED, and that HE ROSE AGAIN THE THIRD DAY according to the scriptures." (1Cor. 15:1-4).
"For by grace are ye saved through faith, and that not of yourselves: it is the gift of God; not of works lest any man should boast." (Eph. 2:8,9).
So here is the Gospel of Christ, that SAVES in this dispensation of the Grace of God.
Paul stated firmly if another gospel is preached than the one he preached, let him be ANATHEMA.
“But I certify you, brethren, that the gospel which was preached of me is NOT AFTER MAN. For I neither RECEIVED IT OF MAN, neither was I TAUGHT IT , but by THE REVELATION OF JESUS CHRIST.”
So what was the Gospel of Christ that Paul received by DIRECT REVELATION FROM THE RISEN CHRIST?”
That’s not in conflict that Paul recieved direct revelation. Of course it is. Galatians 1 is clear that he received it directly.
Catholics believe that only through the merits of Our Lord, Jesus Christ are we saved by Grace. WE MERIT NOTHING ON OUR OWN.
Secondly, Catholics prove Scripture BY Scripture.
In Galatians, if you READ THE ENTIRE BOOK, which is why we do not simply exerpt passages, Paul’s opponents in Galatia wanted to bring the Gentile Christians back into the Old Testament law. These are the works of the law that Paul is fighting against, and they have no place in our justification. Paul is saying in essence that Gentile Christians do not have to be circumcised and live like Jewish Christians in order to be saved.
But Paul speaks about Christians fulfilling the law by following the command to “love your neighbor as yourself” (Gal. 5:14). He then explains that we must show the “fruit of the Spirit” (Gal 5:16–26) and bear one another’s burdens (Gal. 6:1ff) as a way of fulfilling the “law of Christ” (Gal. 6:2). All Paul’s teaching comes down to this: Our own works can never justify us, but works that grow out of faith in Christ are part of our justification. That’s why Paul says in Philippians 2:12 you must “work out your own salvation with fear and trembling.” And that squares with James’s teaching that works that grow from faith justify.
You forgot the second part of Ephesians:
“For by grace are ye saved through faith, and that not of yourselves: it is the gift of God; not of works lest any man should boast.
For we are his workmanship created in Christ Jesus for GOOD WORKS, which God prepared beforehand, THAT WE SHOULD WALK IN THEM.”
