There's some Orthodox who would argue it's 'conceit' that said anyone recived it from CHRIST directly. ;p
Filioque etc.
"Filioque", the way we understand it, was a necessary temporal response to a particular form of arianism emerging at the time in Spain -- very far from Constantinople. In hindsight, the unity of the Church was more important, but the Latin Church was doing what is pastorally should do, albeit lacking in consiliarity.
But look what the Holy Spirit has wrought! You were spared the Reformation! You witness for the Church of the Seven Councils! Rejoice!
