This is factually incorrect. Even though in most European countries there is a formal separation of religion and state, there is nothing that "forbids" any political party from having a strong religious affiliation. In fact, in nearly every European country there are major political parties with a strong Christian affiliation. See: https://en.wikipedia.org/wiki/Christian_democracy

There are even countries which have political parties that are Islamic affiliated.

The separation between religion and state refers to two things: the state not being able to enforce any religious aspects on citizens (freedom TO exercise any religion without interference from government), and religious entities not being able to influence or pressure the government outside the electoral process (freedom TO govern without interference from religious entities). Neither of these things prevents a political party founded on religious beliefs to participate in the electoral process.
