Ugh, it is accurate. If you want to get the whole picture, there are volumes of books that cover the Schism. To be upset that a short article doesn't cover everything is a bit naive.
Michael quarreled with
Pope Leo IX over church practices in which the Roman Church differed from Constantinople,
particularly the use of unleavened bread in the Eucharist.[2] Dissenting opinions were also exchanged over other theological and cultural issues, ranging from the issue of
papal supremacy in the Church to the
filioque clause and other disagreements between the patriarchates.
*BECAUSE first of all Michael was presumptious, arrogant to think he could usurp the role of the Roman Pope.
Most of the time throughout history - these were the men excommunicated and nobody batted an eye but stayed with the ROCK of the Church.
But as time passes, men usually fall away and it was no different in 1054.
Scripture was firm. Jesus was firm and not only did He say what He said but said it was The Father Who chose.
AND now all Three if the Trinity are Involved in the statement of Jesus.
Matthew 16:
13Now when Jesus came into the district of Caesarea Philippi, he asked his disciples, “Who do people say that the Son of Man is?”
14And they said, “Some say John the Baptist, others say Elijah, and others Jeremiah or one of the prophets.”
15He said to them, “But who do you say that I am?”
16Simon Peter replied, “You are the Christ, the Son of the living God.”
17And Jesus answered him,
“Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.
18And I tell you,
you are Peter, and on this rockb I will build my church, and the gates of hellc shall not prevail against it. 19I will
give you the keys of the kingdom of heaven, and
whatever you bind on earth shall be bound in heaven, and whatever
you loose on earth shall be loosedd in heaven.”
20Then he strictly charged the disciples to tell no one that he was the Christ.
To bind or loose is the LAWS of the Church. The laws of the teachings.
What Jesus DID NOT say was - whatever you bind or loose I will not allow....
I will have men argue against it, change it, remove it, fight it, disallow it, and usurp it.
It is always in deferring oneself to the Pontiff of Rome that things can metted out, but never can there be a case of justification to leave the Roman Pontiff without full on error/errors.
