Christ's Church was never destroyed. He still adds people to it just as He did in the first century.
Then why the need for a Reformation--with numerous new denominations--with a different theology?
And why the prophecy here?
Acts 3:21---King James Version
21 Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
That's a restoration, not a Reformation. God's gospel is perfect already, and has no need to be reformed.
Does God add people to His church today--- the same way He did in the NT?
Acts 2:38-42---King James Version
38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
40 And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation.
41 Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.
42 And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers.
That's the doctrine one will find being practiced in The Church of Jesus Christ of Latter-day Saints.
