They *say* is the operative words there. Scripture does not and will not contradict itself.
Now, if YOU and I can see that their teaching contradicts Scripture, then they do too. Their problem is that they deny it and go fishing and rationalizing.
And they're lying because the Holy Spirit would never call what was sin to not be sin any more.
Acts 15:28-29 For it has seemed good to the Holy Spirit and to us to lay on you no greater burden than these requirements: that you abstain from what has been sacrificed to idols, and from blood, and from what has been strangled, and from sexual immorality. If you keep yourselves from these, you will do well. Farewell.
If what they claim is contradicted by teaching in Scripture, then the Holy Spirit is not doing the interpreting, no matter what they claim.
If sacred tradition is not invalidated because of people who have misused it, then neither is the word of God, which is more sure and absolute truth.
