If the authority of scripture is superseded but a little, religion/relationship between God and man can become morphed into superstitious ritual and idolatry.
And when salvation made to be earned [which also is contrary to scripture (Romans 3:23-24, 4:4-5 & 10:1-4)], that's when the spirit of the law fades beyond memory, and religion becomes legalistically abusive (Matthew 23:23, Mark 2:27, Luke 11:46, Matthew 15:1-6).
So the temple of the living God (1 Corinthians 6:20) and the church (1 Timothy 3:15) has since then been made into a physical temple again; as if He needs or requires it (Psalms 50:12).
