Helmut Dieser (born March 15, 1962, in Neuwied) is a German Roman Catholic bishop of the Roman Catholic Diocese of Aachen.
Dieser studied Roman Catholic theology and philosophy in Trier and Tübingen. On 8 July 1989 Dieser became priest. On 5 June 2011 Dieser became ordained titular bishop of Narona. Since 12 November 2016 Dieser is bishop of Aachen.[1][2]
In March 2019, Dieser said, exceptions from clerical celibacy in the Catholic Church should be allowed. In his opinion, there should be a reform of the Catholic sexual morality and sexual acts between homosexual partnerships no longer a sin in Roman Catholic catechism.[3] In June 2020, Dieser said blessing of same-sex partnerships should be allowed in the Roman catholic church.[4]
