The Earl of Shaftesbury and the ‘Papal Aggression’ of 1850 is an interesting example of how a man of sense and humanity can be driven by prejudice into taking a posture that contradicts everything he has striven for. What he did was of less importance than why he did it, for even at the time intelligent men were aware that Shaftesbury was obsessively involved in a storm in a tea-cup.

The term ‘Papal Aggression’ indicates how Shaftesbury’s contemporaries saw the Papal Bull of 1850; this Bull abolished the administration of Roman Catholics in Great Britain by Vicars Apostolic, and appointed instead two Archbishops and twelve Bishops with territorial districts clearly marked out. Shaftesbury was in Scotland recovering from illness when he heard about this. It was, he considered, ‘an act of great annoyance and audacity’ but not contrary to law, and he was prepared to simmer awhile.

When Dr Wiseman was appointed the first Archbishop of Westminster and raised to the dignity of a Cardinal, then Shaftesbury felt that he had no other course but to act, and the publication of the pastoral ‘From out of the Flaminian Gate of Rome’ was interpreted by him as a direct threat towards the Church of England. ‘Catholic England’, wrote the Cardinal, ‘has been restored to its orbit in the ecclesiastical firmament from which its light had long vanished’.
