Since it was the Apostles who taught it, they must have known.

When or where did the Apostles teach salvation by faith alone? Luther's German mistranslation of the Bible does not count.

[irishtenor]

For by grace you have been saved through faith. And this is not your own doing; it is the gift of God.

Note it doesn’t say... it is by grace you have been saved through faith and good deeds, saying the rosary, helping your neighbor, reading the Bible three times a day, and praying before meals. It is by faith, alone.
