Don’t mean to be cynical, but . . . good luck with that.
The CEC, WCC, etc., tend to be comprised of folks who value everything but conviction. In the potentially hostile world that tomorrow’s secular Europe (or islamist Eurabia) may become, there will be increasing demographic and political pressure demanding collaboration; think of it as Islamic-”inclusive” ecumenism – a variant on today’s secularist-”inclusive” ecumenism. In such an environment, only conviction will be able to withstand such forces or pay the price of integrity; whether “red” or “white,” it may require martyrdom either way.
