No the arguement lies in whether in causing the procession of the Holy Spirit towards His manifestation to us, the Father gives to the Son to also be a cause, or whether the Son is a mediate point in the spirit's manifestation, and then whether these positions are truly distinct and irreconciliable.
If your really smart that is the argument ;-)
I read the Creed the "Orthodox way" and I read the Creed the "Catholic way" and I still think of St. Patrick and the shamrock. And then I think of how God has no beginning and no end. And then I realize He is unfathomable and I'm fine with that.
But the arguements I've always heard re: the insertion of the filioque in the Creed by the "Latins" is an arguement on the right of anyone to add anything to the original Creed - the argument over the phrase seems secondary. But I've been wrong a coupla times in my life.
