I was an Eastern Orthodox Catholic and now I’m a Roman Orthodox Catholic - an ORTHO-HOLIC
IMHO - the split between East and West was caused by a number of events - some political - some theological, based on interpretation of clauses of the Creed - i.e. The
filioque - where the Western Catholics added “and the Son” to the clause about the procession of the Holy Spirit in the Creed, which the Eastern Orthodox claim created a hierarchy between the Father, Son and Holy Spirit - which, again IMHO is a matter of interpretation rather than reality. I’ve heard it said that in Latin the expression is more accurately translated “The Holy Spirit proceeds from the Father THROUGH the Son” - whereas in Greek this dimension is lost.
When I recite the Nicene Creed at Mass - I simply mentally insert parenthesis around (and the Son) and this settles it for me - other Easter Orthodox believers may not find that acceptable.
There are many other things - The Supremacy of the Pope, probably being the biggest. However, in every organization there’s always SOMEONE who leads - I think that many of the problems that the Eastern Orthodox Church is having, in terms of growth and in divisions of ethnicity; are due to the lack of REAL conciliar leadership across each of the jurisdictions. I experienced a lot of “infighting” and subtle prejudice between those who favor Russian Orthodoxy and those who favor Greek Orthodoxy. For me it’s a non-issue when you have such able leaders as the current and former Holy Fathers - I have no problem accepting their supremacy as leaders.
What really decided it for me - and it may sound trite - was that in the RCC Mass the emphasis is more on
celebration, while in the Eastern Church is seems to be more like a representation (re-presenting) of the Mystical Supper as a somber event. I once remarked to an Orthodox friend that I often felt guilty for smiling after partaking in the Divine Liturgy!!
In the RCC - the Cross is seen as being transformed into Christ’s throne. In Eastern Orthodoxy it remains a cross.
I miss a lot of things from Eastern Orthodoxy - the liberal use of Incense and bells - the bowing, kissing and prostrating before Icons which inspires reverence. The Paschal night celebrations are marvelous! But IMHO - there is so much in common that I have a lot of hope that one day we will be re-united. The Lord knows that we need to be united now more than ever.
Please note these are my opinions - and I don’t mean to minimize the deep felt feelings of my Orthodox brothers and sisters - but I am glad to be Catholic in every sense of the word.
