Final answer:
The claim that the Commons ordered the destruction of altar rails in September 1641 is difficult to substantiate without clear historical records. Iconoclasm was a feature of religious conflict during the European Reformation era.
Step-by-step explanation:
The statement that 'Commons ordered the destruction of altar rails in September 1641' refers to an event during the English Reformation when the House of Commons took increasingly anti-Catholic measures, including actions against physical symbols of the faith. However, without specific historical evidence mentioning the exact directive in September 1641, the assertion as it stands cannot be validated. Iconoclasm was common in certain periods of religious turmoil in Europe, such as the Protestant Reformation. An example of this can be seen in the attack on the Catholic altar piece in St. Martin's Cathedral, Utrecht, during the Protestant iconoclasm in 1572.
