[Petronski]

I state that Catholics aren't Christians since they aren't saved...

It is not for you to decide if Catholics are save or not.

...and that is due to the fact that Catholicism teaches another Gosepl...

Catholicism teaches the Gospel of Christ.

...that rejects the Protestant view Justification by faith alone.

While protestants teach the Gospel of Luther, Calvin, et al. Sola fide is not biblical. It is a false tradition of vain men.

I state that Catholics aren't Christians since they aren't saved... It is not for you to decide if Catholics are save or not.

I don't decide that, the Scriptures do.

[ ...and that is due to the fact that Catholicism teaches another Gosepl...]

Catholicism teaches the Gospel of Christ.

Not according to the scriptures.

[ ...that rejects the Protestant view Justification by faith alone.]

While protestants teach the Gospel of Luther, Calvin, et al. Sola fide is not biblical. It is a false tradition of vain men.

It is the Gospel of the grace of God and the only Gospel by which men can be saved. (Rom.1:16)
