Benedict XVI has removed the raison d'être of the SSPX

Abishop from the Lefebvrist Society of St Pius X, Richard Williamson, has accused Pope Benedict XVI of being an "anti-Semite" for amending the Good Friday prayer in which the faithful previously prayed for the "veil" to be lifted from the Jews. The twisted logic by which Bishop Williamson arrives at this conclusion is too silly to be worth explaining; suffice it to say that he is the most extreme of the four priests excommunicated when Archbishop Lefebvre consecrated them in 1988 and nothing he says will surprise Catholics familiar with some of his previous statements.
The larger issue concerns the SSPX in general, which has rejected the changes to the Good Friday prayer, claiming that the Pope has caved in to "foreign pressures". Despite Summorum Pontificum, the Holy Father's Apostolic Letter removing the most serious restrictions on the celebration of the pre-Vatican II liturgies, relations between the Lefebvrists and the Holy See seem chillier than ever. If the purpose of the Motu Proprio was to heal this rift, it does not seem to have been very successful.
Yet there is no reason to feel depressed; for the effect of the liberalisation of the traditional Mass has been to clarify both the status of the old liturgy and that of the rebel priests and people who adhere to the SSPX.
Let us put this bluntly: once Summorum Pontificum has been properly implemented — and Ecclesia Dei is working to that end there will be no excuse (if there ever was) for Catholics to belong to the SSPX. Yes, the treatment of adherents of the extraordinary form of the Roman Rite in many dioceses has been indefensible; but that situation is now coming to an end. The Missal of Blessed Pope John XXIII now enjoys equal status to the Missal of Pope Paul VI, even if its use is not the norm. That is a remarkable and wonderful state of affairs that effectively removes the SSPX's raison d'être — unless, that is, the Society's real purpose is to reject the teaching documents of the Second Vatican Council, in which case it has no place in the Roman Catholic Church.
Members of the SSPX who are fundamentally loyal to the Pope are returning to the Church; others, like Richard Williamson, are right to stay in what is fast becoming their own denomination.
