The saying "when in Rome, do as the Romans do," guides us in adapting our lifestyle to the local customs and practices which are normal. Saint Ambrose is supposed to have said in response to St. Augustine, who observed that the Church at Milan did not fast on Saturday, unlike the Church at Rome. St Ambrose's advice was to follow the custom of the Church where one is situated. But when it comes to very personal moral issues, such as divorce, which question human dignity and sacredness, Jesus insists on the law of God above every mere custom. He expects the inter-personal relationships of God's people to be modeled on God's covenantal relationship with humanity and not on an ethics judged solely by the situation. This courageous commitment requires patient waiting and even endurance in suffering.
