There is a terrific article about Pope Benedict XVI and his recent work to unify the Church at the American Spectator.
“…The present pope may not go down as the Great Unifier, exactly. He's likely what people today call "too divisive" to pull that off, and it's hard to see why he would want to. Benedict knows how to use divisions to great effect. He takes Christ's statement from the Gospel of Matthew, "I did not come to bring peace but a sword," quite seriously.
“When a group of traditionalist Episcopalians held a conference in Dallas in 2003 to talk about breaking away from the U.S. Episcopal Church over its increasing liberal drift, then Cardinal Ratzinger sent them a message egging them on. He assured them of his "heartfelt prayers" and said that the "significance of your meeting is sensed far beyond [Dallas] and even in this city, from which Saint Augustine of Canterbury was sent to confirm and strengthen the preaching of Christ's Gospel in England." According to Dairmaid MacCulloch, writing in the Guardian, when the delegates heard this, "There was wild applause."
“In fact, the pope's recent actions with the Anglicans mirrored an earlier act of his papacy that was also hugely controversial but that was seen by outsiders mostly as a family squabble with some ugly repercussions. It involved the Society of Saint Pius X. These were traditionalist Catholic priests who, because of the reforms that followed the Second Vatican Council and especially the de facto suppression of the Latin Mass, formed a rebel sect within the Church.
“The Society's late founder, Archbishop Marcel Lefebvre, was eventually excommunicated when the aging prince of the Church ordained four new bishops to continue his work in 1988, in defiance of the explicit orders of John Paul II. Millions of otherwise loyal Catholics, especially in France, attended the Society's beautiful, ancient Mass because they had a hard time finding it anywhere else.
“As head of the CDF, Benedict pleaded with Lefebvre not to ordain more rebel bishops, but didn't succeed. As pope, he moved to reincorporate the Society into the Church, first, by issuing a universal indult in July 2008 mandating that bishops allow the Latin Mass in their dioceses, and, second, in January 2009, by lifting the excommunications of the four men that Lefebvre ordained bishops. This wouldn't have raised too many eyebrows outside the Church but for the fact that one of those men, Richard Williamson, turned out to be a Holocaust denier and a 9/11 "truther" conspiracy theorist.
“The press had a field day with that one. But there was another story lurking beneath the obvious scandal. Benedict's Latin Mass decree greatly increased the rights of the faithful against their sometimes imperious bishops. Now, a bishop has to explicitly prohibit the Latin Mass, give a good reason for doing so, and risk losing an appeal to Rome. That ended the need for a Society of Pius X as an outside agitator.
“Now, Rome wants more priests trained to perform the Latin Mass, and it wants those parishioners back who had turned to the Society for its ceremony. So it swallowed hard and lifted those excommunications and is in talks to bring the Society's priests back in. If talks stall, expect Benedict to personally intervene.”
