SSPX detente?

The religion editor for Reuters published an article “Catholic splinter group sees no Vatican accord” on the eve of Vatican-Society of St Pius X talks ending but with no resolution. Why this group of priests persists in living outside the Catholic Church and under the unity of Pope Benedict is beyond me. Hubris is a good word but the issues are complex. Certainly there are some legitimate doctrinal issues that have surfaced following the Second Vatican Council on which the SSPX adherents are correct in objecting to. But their manifest schism from the Church of Rome is not the way to renew doctrine and to have care for the salvation of souls. I think Bishop Bernard Fellay is too obstinate to accept any offer of Divine Grace from the Trinity.
