Bart D. Ehrman, The New Testament: A Historical Introduction to the Early Christian Writings, sixth edition (OUP, 2016), 139.
Contrary to what many Christians have thought throughout the ages, for Matthew, following Jesus does not mean abandoning the Jewish Law and joining a new religion that is opposed to it. Even in Matthew’s day some Christians appear to have thought this is what Jesus had in mind – that he sought to overturn the Law of Moses in his preaching about the way of God. For Matthew, however, nothing could be further from the truth.
