Kazimierz Nycz

Cardinal Nycz upholds the Catholic understanding of marriage while showing openness on civil law. In October 2024 he said there should be 'some tolerance' for people who want a form of partnership easier to enter than a civil contract, but that it is important 'to clearly distinguish between the unbreakable, sacramental marriage and any other form of union'. He added that legislation is the role of politicians.

After Traditionis Custodes, Cardinal Nycz said the matter had been dealt with 'too harshly' and could push some people out of the Church. He said the Polish bishops wished to apply the motu proprio generously and that priests already authorised to celebrate the traditional Mass should generally continue, while new priests must request permission from the Holy See. He still allows the traditional rite in his archdiocese.

Cardinal Nycz praised Pope Francis's outreach to the margins of society and called him 'remarkably courageous' for his letter defending Mexican immigrants. He has also welcomed the change to the Catechism on the death penalty as consistent with the development of Church doctrine.

Created a cardinal by Benedict XVI, Cardinal Nycz has publicly backed the direction of Francis's pontificate. In April 2025 he said 'the processes initiated by Francis in the Church cannot be stopped' and that the Church needs 'a creative continuer' who would draw on Francis, Benedict XVI and John Paul II. He also acknowledged that some of the Pope's statements on the war in Ukraine had raised doubts, and has welcomed synodality as a fulfilment of Vatican II.

Cardinal Nycz takes part in ecumenical activities; at the 2019 Week of Prayer for Christian Unity he said 'all eyes are on us Christians' and stressed that words about unity must be matched by deeds. He has also been a member of the committee supporting the POLIN Museum of the History of Polish Jews.

Cardinal Nycz regularly gives interviews, including to media outlets critical of the Church. In 2024 he spoke to Polsat News on civil partnerships, and in 2025 he took part in press conferences and radio interviews about the conclave, in a measured and non-polemical tone.
