His moral leadership has also been recognised at a national level. In July 2025, President Cyril Ramaphosa appointed Bishop Sipuka as a member of South Africa’s National Dialogue Eminent Persons Group, a body tasked with guiding inclusive national reflection and dialogue on the country’s social, political, and economic challenges.
The Archbishop-elect has been vocal on various issues in the South African nation.
In address at the World Council of Churches (WCC) Central Committee meeting in Johannesburg, 18–24 June 2025, Bishop Sipuka urged church leaders and delegates to center their deliberations on the “tangible realities of human suffering” rather than abstract theological debates.
He stressed that authentic Christian engagement must be rooted in compassion, justice, and solidarity with victims of conflict and violence, not merely in political maneuvering or compromise.
Later in August 2025, at the Plenary Assembly of SACBC, Bishop Sipuka delivered a homily lamenting what he described as a shift toward “practical atheism” in South Africa and the region.

Using the biblical image of disciples in a storm, he likened the Church’s current challenges, including falling Mass attendance and societal moral decline, to a boat caught in tempestuous seas, urging Catholics to hold fast to faith amid secular pressures.
At the 2025 G20 Interfaith Forum held in Cape Town, Bishop Sipuka challenged faith leaders to avoid alignment with political elites and instead deepen their pastoral engagement with the marginalized.
He emphasized that authentic Christian leadership arises from “pastoral proximity”, spending more time with the poor and vulnerable than in government offices, and warned against complicity in systems that perpetuate injustice.
Bishop Sipuka has also been active in human rights and ecumenical dialogue.
Earlier in 2025, he called for greater respect for human rights in South Africa on Human Rights Day, urging society to honor the dignity and equal worth of all citizens in the wake of ongoing abuses and social challenges.
Once installed, the 65-year-old Archbishop-elect is expected to serve as the Local Ordinary of the 30,892 square kilometer Archdiocese that has been under the Apostolic Administratorship of Cardinal Brislin.
The Metropolitan See has an estimated population of 276,415 Catholics representing 5.6 percent of the total population, according to 2023 statistics.
