I've been going to a Byzantine Rite Catholic parish for a few years now and when this subject comes up people often want to know the difference between Latin and Byzantine Rites. I usually say its a difference in what is emphasized.
The two sides have identical beliefs. The filioque is not part of the
Nicene Creed and we have the Dormition instead of Assumption. However,
both sides agree that Mary ended up in Heavean body and soul and it is
agreed that the Spirit proceeds through the Son from the Father.
The two sides emphasize different aspects of the same beliefs. For example, Mary is emphasized in the East as Theotokos (Mother of God) and ever-virgin in the West. Both sides believe and teach she is the Theotokos and ever-virgin but each side has its own emphasis.
May God bless all who read my ramblings,
