I think this summs it all up. If the Father gave everything to the Son, then the Son would be the beginning of the Father and the Spirit...indeed absurdity.
The problem is pride. Admitting error would send the Latin Church into an unimaginable crisis of credibility. So, a linguistic formula is being sought that would claim Filioque to be inerrant, yet unnecessary, but not wrong. Unfortunately, that is never going to be enough. I simply don't see the Latin side ever admitting the heresy they embrased one thousand years ago, and a heresy they practiced in some parts of the Patriarchate of the West for 1,500 years.
Filioque is not what we believed "everywhere, always, and by all," and is not Scriptural, but a man-made tradition (Protestants should take note of that!).
