First thing first, I recommend that you take questions about Orthodox Christianity to Orthodox forums where you are more likely to get answers from Orthodox Christians themselves. That said, since I am Orthodox I will offer my answers.
Is it true that Eastern Orthodox Christians wear a cross to show they are baptized members of the church? I heard that it’s given to them at baptism
It is customary for Orthodox Christians to receive a baptismal cross as part of their baptism and chrismation. It is also customary for the baptized Orthodox Christian to wear this baptismal cross once they are old enough to do so.
Is there any solid reason why Eastern Orthodox Christians don’t use 3-dimensional statues like Catholics do or is it purely tradition?
Icons were more prevalent in both early Western and Eastern Christian parishes because it is easier to paint a picture than sculpt a statue. There is nothing inherently wrong with using statues. Orthodoxy simply never adopted the practice.
Pascha, that’s what Easter is called in Orthodoxy right?
Correct.
Is it true some Divine Liturgies are in English and some are not, depending on where you go?
Yes, just as the language in which the Mass is celebrated varies from place to place.
Do Eastern Orthodox Christians believe in Marian apparitions?
Do we leave they are possible? Absolutely. Do we accept all alleged apparitions? Not necessarily.
Has anyone asked you “are you Catholic or Christian?” and if so how do you respond?
Orthodox Christianity is both catholic and Christian. However, because the term “catholic” is almost exclusively associated with the Roman Catholic Church, many Orthodox Christians do not introduce themselves as Catholic because it may lead to confusion.
What’s the Eastern Orthodox position on divorce and how does it differ from Catholicism?
In Eastern Orthodoxy, divorce is seen as a grave sin that ought to be avoided. However, Eastern Orthodox Christianity permits divorce and remarriage in certain circumstances.
