`  == Theological inaccuracy ==  The section on Orthodox theology grounds the Orthodox rejection of the filioque partially on the idea that ``the Father is the God of the Old Testament.``  That has nothing to do with the rejection of the filioque.  The Father, Son, and Holy Spirit are each fully God, without division, but the revelation of God in the Old Testament is, according to Orthodox theology, primarily a revelation of Christ, the Logos.  If no one has any objection, I'll change it.  OrthodoxLinguist`
