re: I've got a magic trick to show you

i dont have all the answers but you are only looking at half of the book. pretty sure somewhere in the new test. that the old test laws are essentially "moot" because of what he said/did/accomplished. i'm the furthest thing from a bible thumper but at least make sure you arent arguing, once again, a moot argument

ETA from a simple google search: Hebrews 8:6 and Hebrews 8:13 would be the applicable verse to this situation.

ETA again: Christians do not have to keep the law of Moses because those laws were a temporary package, designed to be in force only until the Messiah came. Now that he has come and given us a better covenant, the first is obsolete.
