What was the cause of the great schism of 1054 between the eastern and western church?

There had been splits before i believe on three different occasions but this time was more definite due to a culmination of differences. The big one was when the Patriarch of Constantinople excommunicated the Pope after the Popes messengers interrupted a mass at the Church in Constantinople and once it got back to Rome the Pope excommunicated the Patriarch. There were other problems between the two lungs of the Church such as the Western Church added the filioque . The biggest problem that Historians say is there was just a plain language problem between the Latin and the Greek which created misunderstanding of beliefs.And there were also cultural differences which caused different understanding of beliefs. But thank GOD the excommunications have been lifted and the two Churches are getting closer to being one again.
