The Lutheran Church – Missouri Synod ( LCMS ) bars its clergy from worshiping with other faiths , contending " that church fellowship or merger between church bodies in doctrinal disagreement with one another is not in keeping with what the Bible teaches about church fellowship . " In keeping with this position , a Connecticut LCMS pastor was asked to apologize by the president of the denomination , and did so , for participating in an interfaith prayer vigil for the 26 children and adults killed at a Newtown elementary school ; and a LCMS pastor in New York was suspended for praying at an interfaith vigil in 2001 , twelve days after the September 11 attacks . Another conservative Lutheran body , the American Association of Lutheran Churches , is strongly opposed to ecumenical ( more accurately , interfaith ) dialogue with non-Christian religions and with denominations it identifies as cults
