The Religion of the Apostles: Orthodox Christianity in the First Century (Stephen De Young)
Myths about Christianity abound, and some myths even pass as common knowledge. One myth is that Christians, after Jesus Christ started a new religion, worshipped in a very simple manner, revolving around undeveloped doctrines of love and sharing. Only later, we are often told (by both devout Protestants and by unbelievers, advancing different agendas) was this plain worship larded up with new doctrines and liturgies, which are encrustations on true Christianity. Stephen De Young works hard to explode all parts of this myth, explaining in The Religion of the Apostles that the beliefs and worship of the first Christians were essentially identical to those written down some years later, and were not, in most important ways, new at all.
