The Atlantic has a profile of Muslim converts in Germany, with special emphasis on the congregations they are attending. The focus is on Trinity Lutheran Church in Berlin, a SELK congregation in fellowship with the LCMS. The pastor, Gottfried Martens, studied at Concordia Theological Seminary in Ft. Wayne, Indiana.
They have around 1,000 baptized members who are ex-Muslims, with 300 on a waiting list, apparently being catechized. (The Atlantic reporter doesn’t quite understand Lutheranism. It’s kind of amusing to see how she describes catechism and her confusion about crossing herself. But kudos to her and also to her publication for significantly ramping up its religion coverage.) The story describes Germans and ex-Muslims (who outnumber the former) having tea after service, their children playing together, all taking part in the normal workings of a congregation.
