Hello Hive account@manahawkin. Great note. I believe that officially (according to the law of the church in our area), there is no way to unite two religions in one building. This church is primarily Catholic, but due to historical events, it has become a place of attraction for Catholics and Orthodox believers. This is a unique case.
In fact, I would be glad to see one common church uniting all religions. Though I think I've seen one like this once. Your question allowed me to remember another unique church. I will probably visit her soon and tell them about her. Thanks:)😊
