Anyone who argues for the need for something in addition to the redeeming work of Christ is denying the Savior who redeemed us.
I stand on the blood of Jesus. I am part of the temple you accuse me of not seeing, and I stand on that blood. The Jews will sanctify the ground of the new temple with the blood of the red heifer, hence their third temple will stand on that blood.
Salvation is a big word, being built into the Temple is part of my salvation, being able to stand on the blood is my salvation. I get it, you do not understand fully what salvation is, fine, so rule number one, stop accusing the brethren. Stop judging others.
