No, churches are in rapid decline in Europe and have been for decades. Religious decline in the Europe is one of the most dramatic and extensively documented social phenomena in the modern world. You could gather more convincing evidence that bigs are beginning to fly than Christian churches are growing in Europe. (I base these comments on extensive reading of the academic literature for decades and visiting literally hundreds of different churches in dozens of different denominations.)
Among the many books on this trend, some of the best work is by Clive Field, Steve Bruce, Callum Brown, and Ronal Inglehart .
