Why are the easterns in schism with Rome? Because of sin.
We argued with each other for a long time. Rome was right and Constontinople was wrong but both sides were too proud to act with charity to each other.
Then the muslims came. When the muslims conqured Constantinople, they were in communion with Rome. **The muslims basically said that they would cut off all the heads of every Christian who did not swear to break communion with Rome. Many Christians prefered to die but many more felt relieved to not have to follow all the teachings of Christianity to exactness anymore and gladly gave Rome the finger **and allowed a muslim with 86 wives to choose the Patriach for them.
Now in our modern day we are in a situation where reunion, true visiable and open reunion can happen and we should be working twards that. Not by denying history or blaming each other but by looking to the truth.
The Pope, regardless of where his see is, is the visible head of the Church. End of story. No Pope, no true church.
The Filioque is 100% orthodox faith. Greeks who jump up and down and say that it is heresy but have no idea what it means are themselves heretics. The Holy Spirit “procedes” from the Father Through the Son. How do you say that in Latin? Filioque. Please note the verb. Go find the Greek verb and look up its meaning before you attack this because I am right and you will just be creating hate.
Liturgy is valid using Leavened bread or unleavened bread. To believe that only ONE way is valid is heresy.
The Church has the authority to decide that it can use whatever language it wants to perform the liturgy. To believe that Latin Liturgy is invalid because it is not in Greek is a heresy.
Believing that the Bible can only be read in Greek with no translations allowed is heresy. Believing that the Bible somehow trumps the authority of the Church is also a heresy.
Authority in the Church flows like this. God first then the Church. Within the Church Authority rest with the Pope. Under the Pope there is the universal Synod, we call this a council in the west. A council does not trump the Pope and to believe such is a heresy. Under a Council there are the various Bishops of the Church at all levels. Some are Patriarchs, some archbishops or Cardinals but all are Bishops, successors to the Apostles and we faithfull must be loyal to them. Under Bishops are of course our priest who is given charge over our souls. Please note, diacons do not have authority in themselves, they only serve as helpers of the Bishop. Priest do have some authority of their own but may only exersise that authority with the permission of the Bishop. Just as a Bishop has authority, he must only exersise that authority when he is in communion with the Pope because only then is he in communion with the Church. Also note, political leaders have no place in the line of authority within the Church or without.
Under the Church, there is the authority of the Bible. The Bible’s authority depends on the Church’s authority, which depends on God’s authority.
What was a big part of Eve’s sin. She tried to invert the natural order of authority. In the garden of eden authority went from God, to Adam, to Eve to creation. But then Satan came in the form of a created animal and he tricked Eve to accept a snake’s authority. She then tried to impose that authority onto Adam and he accepted it. This was a huge part in their sin.
Scripture, no matter how true and holy, does not trump the Church. Priest do not trump the Bishop. Bishops do not by themselves trump a Council and councils do not ever trump a Pope. The Church never trumps the will of Almighty God. In fact, we know we are in the one and only true church because we give our will over to the will of Almighty God. The Church is here to be holy and do the will of God.
If reunion ever really does happen, it will come about because Catholics and those in schism from the Catholic Church seek to be holy and do the will of God. It will come about by holy men leading the faithful to the truth, full truth of Lord Jesus with not accepting of this or that. Full Truth, no cafateria. No divorce, no contraception, no skipping Mass on Sunday, no giving in to political presure. The one Church worships the One God as that God has commanded us to do.
