Life Wiesemann was born in Herford, North Rhine-Westphalia in the archdiocese of Paderborn. He became a chaplain on 10 October 1985 in Rome. He later served as a priest in Bösperde, a suburb of Menden and provost of St. Petrus and Andreas in Brilon.

Positions In January 2014, Wiesemann supported married priests in Roman-Catholic Church. In February 2022, Wiesemann supported blessings of same-sex unions. He promised to respect the consciences of priests who refuse to bless the unions, while asking them to refer the couples to the diocesan office. This office would then contact another priest willing to bless the union. Remarried couples are to be treated the same way.
