Jesus is not walking on the earth, and Paul died years ago. Justification by men does not constitute approval by God.
Does it say somewhere in the Bible that these Godly practices will come to an end with the death of the Apostles? I never read that.
And besides, Campion already showed that the Jews were doing the same thing in the OT. So if a prophet of God can do it when Christ was not even walking the earth yet, why can't one do it after He came? Do you have any Scripture to back you up on this claim?
Third, your point about the final covenant doesn't hold water, as Paul was doing it with impunity under the very same new covenant that we are under.
