Wijlens was not appointed to the advisory council as a representative of the theology professors, but because of her international contacts and her expertise in canon law, including in the area of sexual abuse by clerics.
Furthermore, following a reorientation of the Johann Adam Möhler Institute for Ecumenics in Paderborn, the canon lawyer was again appointed as a member of the Scientific Advisory Board for the period until 2025 by the President of the Institute, Archbishop of Paderborn Hans-Josef Becker. She was also appointed to the Steering Committee for Orthodox Catholic Dialogue at the Pro Oriente Foundation in Vienna.
