WHERE exactly does the Scripture differentiate between "salvation" and "rewards"?1 Corinthians 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ.
12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
14 If any man's work abide which he hath built thereupon, he shall receive a reward.
15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
Regarding 1 Cor 3:15.
I have seen some Catholics refer to these verses as Scriptural proof for the concept of Purgatory.
Whether you agree with that or not, reward and salvation are used interchangeably in the passage. I don't see "going to heaven, but receiving a lesser reward". Purgatory is a better fit for the passage.
