I will answer you as honestly as I can. When it comes to faith, you can consider me a baby, so there's not much I know about Soteriology. I don't even know what it means.

You can, however, explain it to me so I will be enlightened.
If there's one thing I believe in, though, God gives us the free will so we'll be able to make full use of every gift he has given us, for example, talent. He gives us the freedom to determine the best way we can use it for our and other people's advantage.
As for me--as I can only speak for what I believe in--to believe in the Crucifixion is to have faith on the promises of Christ that we have been saved. It's just up to us to decide if we are going to take the grace of salvation or not. Also, to believe in the Crucifixion is to have the tenacity to be humble and to repent for someone died to pay for our sins.
