The Catholic Church has NEVER modifed dogma to accomodate its members or its leaders.
Luther & Co. and Henry VIII actually deleted the definition of certain sins to accomodate popular opinion or powerful individuals. Doing so was fundamental to the founding of their sects, and is now fundamental to their continued existence. Yet in the long run, there is nothing real that endures in such sects. Why worship a God who heeds the dictates of the popular will of the members?
So, how and why did the filioque get inserted into the Western version of the Creed after many years in which the Popes of Rome upheld the Orthodox Catholic Faith against the influence of the filioque-championing Franks?
For those of us in the East it certainly looks like modifying dogma to accommodate some very powerful folks in the Patriarchate of Rome.
