Best-effort edit based off of your note and image in change #176261596
The image attached has 3 plaques:
1. cultural centre name
2. Serbian-Orthodox church plaque
3. Church Name with the primary language in Greek

I now have to wonder, Is the building fundementally a greek_orthodox church witch hosts serbian_orthodox masses? or vice-versa?
maybe it's not even greek_orthodox but rather greek_catholic?

I have marked it as serbian_orthodox as that is the best data I have, but if i were to guess, it is primarily Greek.

(I assume the language is greek, considering OCR and translation systems say that it is)
