With reference to the DNA tests, Witherington wrote in his blog: "he most the DNA evidence can show is that several of these folks are interrelated…. We would need an independent control sample from some member of Jesus' family to confirm that these were members of Jesus' family. We do not have that at all." This quote clarifies the fact that the documentarians do not believe they have tested the DNA and have proven it to be Jesus. They simply used DNA testing to prove that the "Jesus son of Joseph" and the "Mariamne" in this tomb were not maternally related (i.e. that they did not have the same mother or grandmother). The film asserted that this DNA evidence suggests they were probably spouses. Critics contend they could have been paternally related (e.g. father and daughter, or grandfather and granddaughter), or related by someone else's marriage. Mariamne could just as well have been the wife of one of the other two males in the ossuary.
