Acts 13

After Paul recounted the testimony of the prophets concerning the coming of the Messiah, he teaches -

"Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins:
39 And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses."  (New Testament | Acts 13:38 - 39)

To the wicked priests of Noah, Abinadi also taught -

"...now ye have said that salvation cometh by the law of Moses. I say unto you that it is expedient that ye should keep the law of Moses as yet; but I say unto you, that the time shall come when it shall no more be expedient to keep the law of Moses.
28 And moreover, I say unto you, that salvation doth not come by the law alone; and were it not for the atonement, which God himself shall make for the sins and iniquities of his people, that they must unavoidably perish, notwithstanding the law of Moses.
29 And now I say unto you that it was expedient that there should be a law given to the children of Israel, yea, even a very strict law; for they were a stiffnecked people, quick to do iniquity, and slow to remember the Lord their God;
30 Therefore there was a law given them, yea, a law of performances and of ordinances, a law which they were to observe strictly from day to day, to keep them in remembrance of God and their duty towards him.
31 But behold, I say unto you, that all these things were types of things to come.
32 And now, did they understand the law? I say unto you, Nay, they did not all understand the law; and this because of the hardness of their hearts; for they understood not that there could not any man be saved except it were through the redemption of God."  (Book of Mormon | Mosiah 13:27 - 32)

The Book of Mormon addresses this topic on several occasions what Paul taught in Antioch.  Obviously, Paul had come to understand the purpose and mission of the Savior.

I find Paul's warning then to the Jews to one to all -

"Beware therefore, lest that come upon you, which is spoken of in the prophets;
41 Behold, ye despisers, and wonder, and perish: for I work a work in your days, a work which ye shall in no wise believe, though a man declare it unto you."  (New Testament | Acts 13:40 - 41)

There are even supposed so-called Christians today that are so steeped in tradition that they may be despisers who wonder and perish.
