Are "The Five Conditions" necessary and reasonable?

There is much debate going on inside and outside SSPX circles over "The Five Conditions."

One may ask whether these conditions are "insulting" to the SSPX leadership, as some SSPX supporters insist that the SSPX already adheres to "The Five Conditions."

By and large, this seems to be true of Bishop Fellay, though he recently slipped a bit in this regard:

Bishop Fellay: Pope Benedict is a "perfectly liberal Pope"

Given his record of otherwise prudent and measured statements regarding Pope Benedict XVI, this gaff of Bishop Fellay could easily be overlooked, and likely did not precipitate "The Five Conditions."

On the other hand, an argument could be made that Rome is asking Bishop Fellay to rein in other SSPX leaders.

Maybe a little review is in order to ascertain why such a request might have been necessary. These two entries may serve to illustrate Rome's concern:

Excomm’d SSPX Bp. Williamson on Good Friday prayer: good points but calls Benedict XVI anti-semitic

Williamson: "...modern minds are very sick ...and Benedict XVI has a modern mind..."

Here are several interviews, each of which contain troubling assertions:

An Interview With His Excellency Bishop Richard Williamson

SSPX, The Church & The World: 2008 and Beyond

Finally, a review of Bishop Williamson's own blog entries may be in order. Here's a typical excerpt:

Such is surely the case with many – not all – modernist churchmen, and I would include Pope Benedict XVI amongst them. So he can be objectively insane from the standpoint of the Catholic Faith, and yet subjectively in a kind of good faith. What does this “good faith” matter if he is objectively way off the mark? What matters is that he thinks he is normal and in the truth, so he behaves as though he is, and so he persuades many Catholics that he is. Here is why this crisis of the Church is so terrible – so many cardinals, bishops and priests cannot believe that they or their Pope are in any way off the mark.

Conclusion? – I need not believe that they are not at all cardinals or bishops or Pope, because when virtually everybody is insane, they are that much less necessarily aware that they are not sane. So I can treat the Pope with all the charity and respect due to his exalted position, and I can rejoice in all the objective good that he does, for instance in the recent “Motu Proprio,” but I will do nothing, but nothing, to associate with his insane Conciliar belief-system until it is clear as clear can be that he repudiates both Vatican II and his subjectivism.

Taken as a whole, one could easily understand Rome's concerns. When the public reads "The Five Conditions," and realizes how reasonable they are in view of the links above, pressure will increase dramatically on Bishop Fellay to make this first simple act of submission.

The five conditions could only be seen as harmful by the most schismatic branch of the SSPX, a branch Bishop Fellay might need to trim if he is to hope the SSPX will have any future in the business of saving souls.
