Contrary to Rabbi Singer’s assertions, Mark does not affirm an adoptionist Christology (and in fact affirms Christ’s deity). Though there are undoubtedly more statements of Jesus’ deity in John, it is simply untrue that these claims are absent from the synoptic gospels. Singer’s development arguments regarding the resurrection and anti-Semitism also collapse upon further inspection.
Though the alleged discrepancies offered by Rabbi Singer require some investigation to untangle, closer inspection — and more careful reading of the relevant texts — reveals the arguments to be unfounded. The solutions that I have offered to these challenges are not strained or forced harmonizations, but rather are suggested from within the texts themselves.
