Yes, a Romanian Orthodox can marry a Christian from another denomination, but the couple may need to seek permission from the Orthodox Church. The church typically requires that the non-Orthodox partner is baptized in a Christian faith and may also encourage the couple to participate in pre-marital counseling. The ceremony may take place in an Orthodox church, but specific guidelines can vary by parish and bishopric.
Yes, if she converted to Christianity.
Macedonian orthodox like Athenian orthodox and Thessalian, Epirotian, Thracian orthodox can all marry in the Greek Orthodox Church no matter where in Greece they hail from. The foreign church of the Former Yugoslav Republic is a schismatic church and not recognized by the ecumenical patriarchy of Constantinople as an orthodox church. Therefore no Greek, whether Macedonian, Athenian, Thessalian etc can marry in the church of the former Yugoslav Republic but the various ethnicities of the Former Yugoslav Republic who follow their Christian church can marry in a Greek Orthodox Church.
That person must needs to be baptised into the Orthodox Christian Faith before being able to marry in the church.
