Here's are the anti-Christian implication of saying that salvation "is" justification and sanctification: It conflates two different kinds of "being saved". It implies we are saved by our sanctification in the same sense that we are saved by our justification. It contradicts "saved by faith alone" because it implies we are saved by sanctification and by faith. No one intends to imply we are saved by more than faith because this is contrary to our confession and is unbiblical. None-the-less, that is a the implication of saying that salvation is justification and sanctification at the same time. Salvation refers to both, but not both in the same sense. If we do not preserve those distinctions, we are not teaching the Gospel of the Bible and our confessions.
