Another view is that the exception is not a part of Jesus's teaching, but rather a comment indicating that adultery automatically led to divorce under the law of the time, and that Jesus may very well have disagreed with this law. Instone-Brewer sees no evidence that this is how the law worked in that era, however. Following their reading of the verse, Protestant churches give prominence to the Gospel of Matthew over Mark and Luke and accepted adultery as a valid grounds for divorce. They also often believe that an innocent divorcee can freely remarry afterwards. That adultery is a valid reason for divorce is the standard Protestant position. This interpretation was first advanced by Desiderius Erasmus, and received the backing of Martin Luther, John Calvin, and most other major Protestant thinkers. For many centuries there was debate over this issue in the Roman Catholic Church. Major thinkers such as St. Augustine supporting adultery as the valid reason given in this verse for divorce. However, at the Council of Trent in 1563 the indissolubility of marriage was added to the canon law. Since that day Catholic doctrine has been that divorce is unacceptable, but the separation of spouses can be permitted. The main argument against this translation is that Matthew has just been discussing adultery in the previous antithesis, and there used the specific term /moicheia, rejecting the vaguer /porneia. Marital immorality Some translators believe that this verse means divorce is allowed on greater grounds than just adultery. Swiss reformers Huldrych Zwingli and Heinrich Bullinger both read porneia as referring to all manner of marital immorality, including spousal abuse and abandonment. British Archbishop Thomas Cranmer, who served under King Henry VIII, listed a considerable number of valid reasons for divorce, but this never became standard Anglican doctrine. The Church of England instead took a far more restrictive view, and adultery was one of the only legal reasons for divorce in Britain up to the twentieth century. The same was true in many parts of the British Empire and the United States. Many mainline Protestants churches have accepted a broader translation of porneia than just adultery, and now support a wide array of valid reasons for divorce. One modern view is that, since throughout the Sermon on the Mount Jesus condemns the excessive legalism of his day, delineating specific views of divorce from the exact wording of a piece of scripture
