So you are saying those under the New Covenant, which has made the Old Covenant obsolete (Hebrews 8:13), are to obey the Old Covenant food laws, defilement of person laws, cleansing laws, feasts, seasons, etc. and the Decalogue.
Is that correct?
Food laws because that which is unclean in respect to animals still is and is not healthy to eat. Personal Defilement in respect being unclean and a biohazard is still true. And if you don't think so go play with a corpse or human waste every day unprotected and see what happens.
Having relations with a relative or animal is still an issue, right? The latter isn't even mentioned in the NT so it must be okay to do so according to the theology you purport.
It was not made obsolete it was made old. How do we know because if it were obsolete then it would not be becoming obsolete, GROWING OLD near to disappearing as the text states. It would be obsolete good for nothing, gone.
(LEB)
Heb 8:13 In calling it new, he has declared the former to be old. Now what is
becoming obsolete and growing old
is near to disappearing.
The reason he states that it is old is because he is stating, calling the second New. If some thing is new there must be something that is old. So with that in mind, it is growing old or becoming obsolete and is ready to vanish away. Not vanished away, is vanishing away.
The Old Covenant is the law. It will be as long as sin is in this world for they tell us what sin is and are what bring us to Christ. Rom 3 and Gal 3.
Until people accept God's Spirit in their hearts there will be a need for that which was written on stone and parchment to lead them to Christ, (Gal 3) so that which was without will be within.
Yes the Spirit convicts us of sin, but through the Law is the knowledge of what sin is.
As long as sin is in the word there is a need for the law. Where no Law is no transgression.
