Berlin (ENI). For the first time since membership records have been kept, more Germans departed the Roman Catholic Church than were baptized into it in 2010, according to new data from Germany's Catholic Conference of Bishops. The new statistics, which were released with little analysis or comment, showed 170,339 baptisms for the year, and 181,193 departures from the church. However, 3,576 new members, and more than 7,400 returning Catholics, joined the church last year. [114 words, ENI-11-0405]
