Prime Minister Recep Tayyip Erdogan said on Tuesday that "if EU is not a Christian Club, it should admit Turkey."
“When EU admits Turkey, then EU won`t be a Christian Club, but an address where civilizations meet. If this is not the case, you can’t claim that EU is not a Christian Club,“ told Erdogan at a seminar organized by Turkey`s Religious Affairs Directorate. [Source]
If the EU was a Christian Club it wouldn’t have included most of Europe. Europe is so Christian that today Spain legalized same-sex marriage.
